Wide Field Camera 3 Instrument Handbook for Cycle 19 - Space ...

4 Chapter 1: Introduction to WFC3
1.4 Special Considerations for Cycle 19
1.4.1 Current Instrument Status
WFC3 is operating as expected on HST, with its detectors at nominal setpoints of
–83°C (UVIS) and –128°C (IR). There are no significant anomalies in its
performance.
1.4.2 Ongoing Calibration
At the time of this writing, cycle 17 calibration observations have been completed
and cycle 18 calibration observations have begun. Descriptions of the calibration plan
for each cycle are given in Appendix E. Much of the analysis of the cycle 17
calibration programs has already been documented in WFC3 Instrument Science
Reports published on the WFC3 Web site; documentation of the remaining analysis is
on-going.
Proposers and users of WFC3 should monitor the Cycle 19 announcement Web site
for the latest information:

Additional information will be released as part of WFC3 Space Telescope Analysis
Newsletters (STANs) and other updates posted directly to the WFC3 Web site:
