In this STAN, the STIS Team presents a new CCD cosmic ray monitor, as well as updates to the latest version of the STIS Data Handbook, a new Jupyter notebook on Low Count Uncertainties in STIS, and an instrument science report on Updating the Sensitivity Curves of the STIS Echelles (Post-SM4).
This STAN is focused on providing information and guidelines for the preparation and submission of HST Cycle 32 GO Phase II proposals, for both new and experienced users of STIS. The first section gives tips and tricks for the recently announced Reduced Gyro Mode operations, followed by an updated listing of policies, tips, and tricks for preparing successful Phase II proposals. The section on STIS instrument news includes new recommendations for wavecal exposure times for some FUV settings. The section on STIS resources lists some recently developed software tools for the examination and analysis of STIS data and notes several recent STIS presentations and Instrument Science Reports.
In this STAN, the STIS Team presents Cycle 32 updates to documentation and news to STIS users submitting Phase I proposals, as well as updates regarding stis_cti and time dependent sensitivity.
In this STAN we announce the delivery of the Hubble Advanced Spectral Products (HASP) program, as well as summarize the STIS presentations given at the 243rd American Astronomical Society (AAS) meeting in New Orleans.
This STAN is focused on providing information and guidelines for the preparation and submission of HST Cycle 31 GO phase II proposals, for both new and experienced users of STIS. The first section gives an updated listing of policies, tips, and tricks for preparing successful phase II proposals. The section on STIS instrument news includes new recommendations for wavecal exposure times for some FUV settings. The section on STIS resources lists some recently developed software tools for the examination and analysis of STIS data and notes several recent STIS presentations and Instrument Science Reports.
In this STAN, we announce the delivery and implementation of updates to the reference files for the STIS NUV time-dependent sensitivity and for selected STIS spectroscopic and imaging modes contained in the third installment of the STIS flux recalibration effort.
In this STAN we announce the alpha release of the Pandeia-based ETC for HST instruments and the complete delivery of the updated G750L reference file.
In this STAN, the STIS Team presents Cycle 31 updates to documentation and news to STIS users submitting Phase I proposals, including updates to the FUV-MAMA dark rate adopted for ETC v31.1. Additionally, we recapitulate STIS' posters and presentations at the 241st AAS Winter conference that may also assist users submitting a proposal.
In this STAN we announce the delivery of updated reference files for the second STIS flux recalibration release and a presentation poster detailing these updates at the upcoming winter AAS, new introductory Jupyter Notebooks, and the stenv migration.
This STAN discusses policies, tips and tricks for preparing and submitting Phase II Proposals ahead of the Cycle 30 Phase II deadline. It also includes STIS instrument news on exposure times for wavecals. The third article summarizes the latest software tools for data analysis, namely Coronagraphy Visualization tool, Defringing package, and a DrizzlePac notebook. The final article provides summaries of recent STIS presentations, Instrument Science Reports, and papers.
In this STAN we announce the delivery of updated reference files for the first STIS flux recalibration release and a new Jupyter Notebook for aligning and combining STIS images with DrizzlePac.
This STAN includes updates to the available STIS observing modes for Cycle 30 Phase I and details of the increased temperature of STIS following its latest recovery.
In this STAN we announce the delivery of a new version of the Image Photometry Table (IMPHTTAB) for STIS and the end of HSTCAL support for RHEL 6.
Given the changes in the spectral energy distributions (SEDs) of the three primary standards, and re-examination of the spectral flux of Vega, all of the HST flux calibrations are being updated to achieve the originally established precision. The STIS team is currently working on deriving new zeropoints and sensitivity curves for the different imaging and spectroscopic modes. In this STAN article, we cover the updated timeline and plan for a total of four flux recalibration releases. We also present a new STIS Flux Recalibration webpage that will contain the latest information on the recalibration effort.
This STAN offers a set of tips and tricks for preparing and submitting Phase II Proposals ahead of the Cycle 29 Phase II deadline. Additionally, this STAN also provides an article discussing the defringing of STIS CCD G750M/G750L spectra.
