In this STAN we discuss items of interest to those who are preparing Phase II proposals for Cycle 31 and the incorporation of updated dark rates into the COS exposure time calculators.
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 a COS poster to be presented at the 242nd AAS meeting and inform users of the alpha release of a revised exposure time calculator for Hubble.
This STAN describes the Alpha Release of the Pandeia-based HST Exposure Time Calculator (ETC), updates regarding SBC Dark Rate Monitoring, and the release of acstools version 3.6.1.
Contents: 1 WFC3 at AAS 242! 2 Alpha Release of the Pandeia-based HST Exposure Time Calculator (ETC) 3 New WFC3 Jupyter Notebooks: Correcting for IR Variable Background 4 A Novel Method for Aperture-Correcting WFC3/UVIS Spatial Scans 5 Procedural Updates to WFC3/UVIS Superbias Reference File Creation 6 New Documentation
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.
This STAN describes a new ACS Observing mode, Imaging Spectropolarimetry, and the release of HSTaXe Version 1.0.3 and HST Cycle 31 ACS Documentation.
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 discuss the release of Cycle 31 documentation and news of interest to those who may submit Phase I proposals to use COS, including a discussion of G160M use at LP6 and an updated listing of dark rates. We also announce the delivery of a new gain sag table.
HST Cycle 30 is extended by two months while HST Cycle 31 will be shortened by two months.
Contents: 1 WFC3 at AAS 241! 2 STENV Released to Replace Astroconda 3 WFC3/UVIS Postflash: Change to Time-Dependent Reference Files 4 New Version of HSTaXe Released! 5 New Documentation
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.
In this STAN we discuss the availability of stenv as a replacement for Astroconda. We also describe COS posters to be presented at the 241st AAS meeting and announce a new version of the COS Data Handbook.
This STAN describes updates to ACS software tools, ACS/WFC sky backgrounds, corrections to the pre-defined dither pattern ACS-WFC-DITHER-BOX, and the replacement of Astroconda by stenv.
