This STAN is focused on providing information and guidelines for the preparation and submission of HST Cycle 33 GO Phase II proposals, for both new and experienced users of STIS. The first section gives policies, tips, and tricks for preparing successful Phase II proposals, followed by STIS instrument news, including recommendations for wavecal exposure times for some FUV settings. The section on STIS resources lists some software tools for the examination and analysis of STIS data. This STAN also includes updates to the STScI Helpdesk.
In this STAN, the STIS team presents updates on the STIS flux recalibration of the M-modes (release 4), as well as information on the relevant STIS presentation that will be given at the 246th American Astronomical Society (AAS) meeting in Anchorage, Alaska.
In this STAN, the STIS Team presents Cycle 33 documentation updates and news to STIS users submitting Phase I proposals, as well as updates regarding the STScI Helpdesk, updates to the FUV-MAMA Time Dependent Sensitivity corrections, and improvements to the post-SM4 STIS NUV-MAMA dark correction.
In this STAN, the STIS team presents new Jupyter Notebooks on Hubble Advanced Spectral Products (HASP) for data diagnostics and wavelength adjustments, as well as a tool to test coronagraphic observation feasibility. The STIS team also presents a new Instrument Science Report on STIS Cycle 30 Calibration Programs and summarizes the STIS presentations given at the 245th American Astronomical Society (AAS) meeting in National Harbor.
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 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.
