Cycle 25 Calibration

11/2017 - 10/2018 (12 months)

In Cycle 25 the WFC3 team will carry out an extended calibration program to monitor the behavior of the UVIS and IR channels and to provide the best calibration data for scientific programs. The results of these calibration programs will be documented as they become available via Instrument Science Reports on the WFC3 ISR webpage.

Cycle 25 calibration plan was designed to:
