STScI is operating and takes pride in serving the astronomical community. Read our response to rapidly changing circumstances due to COVID-19 and stay informed about which STScI events have been cancelled or rescheduled.
This STAN provides information about updates to CALSPEC and the schedule for implementing changes to flux calibration for HST instruments, a discussion about how to access the correct coordinates for targets with proper motions in APT, and an update on the STIS python defringing tools, which are now available in the stistools package.
Ahead of the upcoming Cycle 28 Phase II deadline, this STAN provides information regarding STIS best practices for submitting Phase II's. In addition, information regarding updates to the STIS Exposure Time Calculator for Cycle 28 Phase II, new posters from the recent American Astronomical Society meeting, and information regarding the recent redelivery of several super-dark and super-bias reference files is available in this STAN.
This STAN provides information regarding the updates made to the STIS Exposure Time Calculator (ETC) for Cycle 28 Phase I, news regarding the sensitivity recalibration of the E140M grating and the delivery of new PHOTTAB and RIPTAB files in support of this recalibration, updates to the NUV-MAMA dark rate, and the status of a new suite of Python STIS Defringing Tools.
This STAN provides information about best practices when submitting Phase II proposals, notification of a recently-published paper in JATIS regarding coronagraphy with STIS, details about the STIS data handbook update, and information about a new job opportunity at STScI.
This STAN provides information for Phase I proposals, including information about relevant posters presented at the most recent AAS in January, post-safing updates, and ETC updates.
This STAN provides various updates to STIS proposing, including changes to the STIS review process for PIs, common acquisition errors and how to avoid them, and how high jitter can impact coronagraphic data.
This STAN provides various updates to STIS calibration, including the Exposure Time Calculator (ETC), the new E140M blaze shift reference file, the current levels and impact of jitter, spatial scanning, and the reprocessing status of pre-SM4 data.
This STAN describes various updates to STIS calibration, including the geometric distortion, time dependent sensitivity, echelle blaze function, and the cosmic ray rejection algorithm.
In this STAN we provide updates on STIS to users preparing a program for the Cycle 25 HST Phase 1 deadline.
This update brings new read noise values for the STIS/CCD and shares information on how to subscribe to separate STIS and COS STANs after the split in 2016.
