Calibration Programs

Calibration programs monitor STIS performance and provide information needed to calibrate supported observing modes. Each cycle, a set of regular (and occasional special) calibration programs is assembled by the STIS team, reviewed by the Science Mission Office, and approved by the Director. The following tables list all of the STIS calibration plans — first in summary, then in detail for each cycle.

Team Lead: Joleen Carlberg

Calibration Lead: Serge Dieterich

Calibration Program Summaries

The final calibration plans describe briefly the purposes, required accuracies, and resources needed for the calibration programs executed in each cycle.  For many years, the results of all of the calibration programs were summarized in Closeout Reports published at the end of each cycle.  As the behavior of STIS has been fairly stable, however, those results are now typically reported in less frequent, but more focused Instrument Science Reports.  The results for the more frequently executed (daily, weekly, monthly) monitoring programs are presented in regularly updated plots available on the Monitors page.  In the tables for the individual cycles (below), the program number link in the ID column gives the program status; the phase I and phase II documents give detailed descriptions of the programs, as proposed and as executed.
