  JWebbinar	Content	Dates Held
  37 - Planning Solar System Observations with JWST	JWST is capable of observing the majority of solar system objects found beyond the Earth's orbit, such as asteroids, giant planets and their satellites, comets, and trans-Neptunian objects. Solar system targets may present additional challenges when planning observations, such as their apparent rates of motion, proximity to bright sources, or ephemeris uncertainties. This JWebbinar will focus on how to use available tools to determine valid observing windows for solar system targets, estimate signal-to-noise ratios for extended sources in the ETC, as well as create solar system targets, visualize target ephemerides, and specify constraints in APT.	September 17, 11 am-1 pm (US Eastern Time)
  36 - What’s New in JWST Cycle 4	This JWebbinar will cover updates in Cycle 4 to JWST proposal preparation tools and policies of which JWST proposers should be aware. We will discuss updates to the Astronomer’s Proposal Tool (APT), the Exposure Time Calculator (ETC), and the duplicate observation checking tool. We will also cover changes in the Call for Proposals, including the reduction of page limits and revisions to size and science categories.	September 10, 11 am-1 pm (US Eastern Time)
  35 - NIRCam Short-wavelength Grisms: A Primer for TSOs	This webinar will cover implementation of time series observations using NIRCam's Dispersed Hartmann Sensor (DHS) grisms in the short-wavelength channel, which are being introduced for JWST Cycle 4. The DHS enables 0.6 to 2.3 µm low resolution spectroscopy simultaneously with the long-wavelength grism (2.4 to 5.0 µm) for NIRCam Grism Time Series Observations. The capability improves the bright limit for such observations, and relies on rather novel new subarray operations. Technical aspects of proposal planning will be highlighted, and a few scientific use cases of relatively bright transiting exoplanets will be presented.	August 29, 11 am-1 pm (US Eastern Time)
  34 - Introduction to WebbPSF: Modeling the Inflight PSF for JWST	In this JWebbinar, we will cover the basics about simulating Webb’s PSF by using the inflight measurements of the optical performance of the telescope via Optical Path Difference files. Then we will introduce different tools and functions that allow the user to setup their simulations directly from the observations, to understand how the optical performance of the telescope might affect PSFs in science data and, finally, to use WebbPSF simulations to perform basic operations in science observations like PSF subtraction.	July 16, 10 am-12 pm (US Eastern Time)
  33 - JWST NIRSpec MOS Data Reduction	This webinar will cover NIRSpec MOS (multi-object spectroscopy) data reduction by the JWST pipeline with example notebooks. We will cover recent pipeline updates that deliver improved spectra with default settings. We will also discuss lingering caveats, workarounds, and techniques to reprocess data, including editing the MSA metafile and master background subtraction.	June 27, 10 am-12 pm (US Eastern Time)
  32 - JWST Data Analysis with Jdaviz	Introduction to the Jdaviz visualization package. Presenters will provide examples of the latest developed features available in the various configurations (Specviz, Cubeviz, Mosviz, Imviz, and Specviz2d) and will guide attendees through basic and advanced workflows to analyze JWST spectra and images.	May 22, 10 am-12 pm (US Eastern Time)
  31 - Pipeline Reprocessing of JWST Imaging Data	This webinar will give an overview of the JWST science calibration pipeline and demonstrate how to process JWST NIRCam and MIRI Imaging observations from uncalibrated images to drizzled mosaics. The webinar will include examples on running the pipeline with custom settings, and also show how to incorporate manual processing to address common imaging issues.	February 15, 10 am-12 pm (US Eastern Time) February 16, 2-4 pm (US Eastern Time)
  30 - MOS Planning with MPT using an Example Science Case	The MSA Planning Tool (MPT) can be used to create NIRSpec multi-object spectroscopy (MOS) observations that achieve desired science goals. Using a real science program as an example the presenter will demonstrate how instrument and observational constraints inform MOS planning strategies in MPT.	January 23, 10 am-12 pm (US Eastern Time) January 24, 3-5 pm (US Eastern Time)

September 27, 9-11 am (US Eastern Time) September 28, 2-4pm (US Eastern Time)
  26 - Introduction to the JWST Exposure Time Calculator for Cycle 3	This JWebbinar will focus on the Exposure Time Calculator (ETC), one of the possible entry points when constructing a JWST proposal. The ETC provides many options that contemporary calculators do not, which can be both helpful and daunting. The purpose of this JWebbinar is to first walk through ETC usage linearly to obtain results for a straightforward observation of a point source, followed by the inclusion of more advanced ETC features for more complex observations. These advanced features are "modular" in the sense that multiple, or only one, can be used for any given ETC calculation, so the various options will first be presented separately, then combined to represent real use cases.	September 21, 2-4 pm (US Eastern Time) September 22, 10 am-12 pm (US Eastern Time)
  25 - MAST: The JWST Data Archive	Investigators who intend to propose for JWST observations in Cycle 3 will benefit from learning about MAST tools to search for existing or anticipated data that may help their research programs, and to discover potential duplications with observations they would like to make. This JWebbinar will include presentations and notebooks for graphical and scripted queries of MAST holdings, and tips for evaluating potential duplications. We will also offer tips and advice for retrieving JWST data, and provide links to documents and other resources for visualizing advanced JWST data products. There will be ample time during the workshop for participant questions and answers.	September 19, 9-11 am (US Eastern Time) September 20, 2-4pm (US Eastern Time)
  24 - Jdaviz, the Visualization Tool for JWST	Introduction to the Jdaviz visualization package. The presenters will describe the newest features available in the various configurations (Specviz, Cubeviz, Mosviz, Imviz, and Specviz2d) and will guide the attendees through basic and advanced workflows to analyze JWST spectra and images.	February 13, 2023 - 2 pm (EST) February 14, 2023 - 11 am (EST)

• Frequently Asked Questions

  Q. Why do you limit attendance to JWebbinars?

  A. To maximize the interaction between the lecturers and the audience.

  Q. What happens if all events are fully booked?

  A. You can still register and will be added to a waiting list. If people cancel, we will go down the list to fill their spots. We will also consider organizing additional events to reach as many people as possible.

  Q. Who should I contact if I have problems downloading or running the material posted after the event?

  A. You can reach out to the JWST Help Desk.

  Q. What do I need to set up my computer to use the online material?

  A. Instructions can be found in the README file that comes with every webinar.

  Q. How do I get started with Python?

  A. If you're new to Python a great place to start is the official Python getting started page: https://www.python.org/about/gettingstarted/

  Below are several resources to get you started learning Python if you are not familiar with Python:

  • https://docs.python.org/tutorial/
  • https://realpython.com/
  • https://docs.python-guide.org/intro/learning/

  Or, if you are familiar with Python or similar programming languages, but not the scientific programming ecosystem in Python:

  • https://learn.astropy.org/
  • https://realpython.com/numpy-tutorial/
  • https://github.com/rougier/numpy-100
  • https://matplotlib.org/stable/gallery/index.html

  Q. How do I use the material on Github?

  A. To use the material on github, you will need to download the notebooks to your local directory. You will then need a Python environment set up that is capable of running Jupyter notebooks. If you are new to Python, you may want to review these instructions for some resources on how to install and learn the basics of Python. Depending on your preferences and system choices, you may find the install instructions there sufficient, but note that many scientists find it easier to use the Anaconda Python distribution and package manager. 

  Each webinar will require a certain set of packages. For detailed instruction, you can refer to the readme files of each JWebbinar branch in the github repository.
