JWEBBINARS

Learning JWST Data Analysis With the JWebbinars

STScI hosts JWebbinars to teach the JWST community about tools and methods to analyze data from the James Webb Space Telescope. Each JWebbinar provides virtual, hands-on instruction on common data analysis methods for JWST observations.

Typical JWebbinar topics include:

Overview of data analysis tools and data products
The JWST pipeline for imaging
The JWST pipeline for spectroscopy
Analyzing IFUs and spectral cubes
Analyzing MIRI photometry
Analyzing time series spectroscopy
Accessing data in MAST

The JWebbinars are led by experts from STScI and the JWST Observer community. Participants are given hands-on experience with the data analysis tools. A virtual programming environment is provided so that participants will not be required to install software prior to attending the event.

The JWST data analysis ecosystem is based on Python and it is recommend that participants be familiar with basic Python coding and the Jupyter notebook interface to get the most out of the JWebbinars.

JWebbinar Registration

To put in your request to register for a JWebbinar, please click on the links below. For each event, multiple dates are proposed. The dates actually offered will depend on the number of people interested in attending and their availability. Events will be populated to maximize participation while keeping the class sizes manageable. More than one time slot will be offered if the event is especially popular. After registration closes, you will receive an email with the date and time of the event you are registered for. If still interested, you will have to confirm your participation by replying to the email. If events have reached capacity, you will receive an email informing you that you have been placed on a waiting list. NOTE: Emails will come from jwebbinars AT stsci DOT edu. You should make sure your spam filter does not block emails from this address.

Recordings of the JWebbinars and the accompanying material will be made available shortly after the class meets. Even if you plan to only use the offline material, if you register you will receive an email when the materials are posted to this website. Materials and Videos are available below.

July 15, 2022 - 11 am (EDT)	Registration is closed
17 - MAST: Retrieving and Downloading Data	This JWebbinar demonstrates how to search the MAST archive for JWST data. We cover the features of the Portal Interface, customizable programmatic searches through two Jupyter Notebooks, and talk about creating DOIs (as requested by the mission) to promote reproducibility and increase your citation count. We do this in three mini-sessions where you follow along. Each session is followed by dedicated time for Q&A: We start with a brief overview of the Archive itself, then explore the features of the MAST Portal user interface, including basic/advanced search and subscription notifications. (~30 mins.) Next, we look at two Jupyter Notebooks: one analyzing exoplanet spectra, and the other looking at sources in a crowded field to retrieve the products you need to extract your own spectra. (~40 mins.) We close the session by going over DOIs; MAST offers a convenient way to create custom DOIs that permanently link to the raw data you used in your analysis. (~20 mins.)

Frequently Asked Questions

Q. Do I have to register to use the offline material?

A. No, but if you register we have your email on file and we can communicate eventual updates to the material and eventual new dates for the event.

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. I filled out the registration form, how do I know which class time to attend?

A. An email will be sent to the address provided with the date and time of the JWebbinar you are registered. If no more slots are available, you will be put on a wait list.

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:

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

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.
