This STAN describes full support for ACS in Cycle 33 and prospects for future cycles, CR-SPLITs disallowed in Cycle 34 Phase II programs, empirical SBC backgrounds available in ETC 34.1.1, recommendations for observations of extended sources in light of CTE degradation, and updated documentation and notebooks.
In this STAN, the STIS team announces the release of a new Hubble Spectroscopic Legacy Archive that encompasses all publicly available COS and STIS spectra including more than 60,000 datasets and over 6,000 individual targets. The STIS team also presents four new Instrument Science Reports that were published between July and September.
In this STAN, the COS team announces the release of a new Hubble Spectroscopic Legacy Archive that encompasses all publicly available COS and STIS spectra including more than 60,000 datasets and over 6000 individual targets. The COS team has also updated the Instrument Handbook to version 17.1 and the Data Handbook to version 6.0.
Contents: 1 Improvements to the WFC3/UVIS Saturation Map 2 Improved UVIS Aperture Corrections Derived from Focus Diverse PSF Maps 3 PSF quality under Single Star Guiding 4 New Documentation
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, we cover major reference file updates improving FUV calibration, two new COS FUV lifetime positions for Cycle 33, Phase II submission best practices, and the COS team’s AAS presentation previewing the new Hubble Spectroscopic Legacy Archive.

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.
This STAN describes STScI Helpdesk updates and Cycle 33 proposal reminders.
In this STAN, we discuss items of interest to those who are preparing Phase I proposals for Cycle 33, provide updates on recent instrument calibration efforts, and share information on updated contact information for the STScI Help Desk.
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.

This STAN describes the new serial CTE correction introduced to CALACS, documentation for HST Cycle 33, a new “fleck” on WFC detector and corresponding updates to the BPIXTAB reference file, and ACS posters for the January 2025 AAS meeting.
In this STAN, we discuss upcoming COS posters at the 245th Meeting of the American Astronomical Society and announce the release of two new notebooks for the Hubble Advanced Spectral Products (HASP) that help users conduct data diagnostics on HASP coadds and apply custom wavelength shifts. Additionally, a new COS notebook is available to assess observing exception reports.
