Overview
WFC3 Calibration Plans
Initial calibration of WFC3 has taken place on the ground in simulated orbital conditions. Shortly after launch, observations will be used to assess the on-orbit performance of the camera during a period called SMOV. As with the other HST instruments, calibrations will be periodically updated through new observations campaigns every year. The results of these calibration programs will be documented as they become available via Instrument Science Reports on the WFC3 ISR webpage.
A summary of HST calibration in the current cycle, and a comparison with prior cycles, may be found on the HST Calibration Plan webpage. Statistics on WFC3 usage for science programs may be found on the Instrument Usage webpage.
Cycle 27 Calibration
11/2019 - 10/2020 (12 months)
In Cycle 27 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 Cycle 27 calibration plan was designed to:
• Maintain and update the standard reference files (biases, darks, linearity, CTE traps, UVIS anomalous QE pixels, post-flash)
• Monitor the health of the instrument (throughput, gain, hysteresis, bad/hot pixels, sink pixels, CTE decline, stability of the post-flash LED, filter transmission, state of the CSM, number of IR blobs, wavelength and flux stability of the grisms)
• Support new initiatives and obtain supplemental (non-routine) calibration data
In this cycle, two standard monitoring programs have been restructured from Cycle 26. These programs (16021, 16030) were designed to:
• Quantify losses in the UVIS sensitivity using spatial scans (previously called ‘UVIS Contamination Monitor)
• Monitor the ‘UVIS and IR Photometric Calibration’ via staring mode observations of HST standards
Five new calibration programs will supplement the standard monitoring. These programs (16020, 16022, 16023, 16029, 16031) were designed to:
• Measure the stability of the tungsten lamp output immediately after turn-on
• Refine the UVIS grism wavelength calibration across the entire detector with better 2D sampling
• Finalize the flux calibration of the UVIS grism with similar spatial sampling as for the wavelength calibration
• Recheck the optimal UVIS background level to mitigate CTE losses
• Check for time dependent sensitivity in the IR detector grisms and filters

In this cycle, two new calibration programs will supplement the standard monitoring data. These programs were designed to:
- Cross-calibrate the HST focus values derived from the OTA Focus monitor (based on UVIS/F410M observations) with the focus values derived empirically from the WFC3/UVIS PSF database, which has many more F606W observations
- Characterize the decay of IR persistence at short time-scales (t <300 sec), where the observed residual signal deviates from the current power-law model

Ground Testing
WFC3 has undergone several iterations of fully integrated instrument testing. This testing took place at Goddard Space Flight Center (GSFC). During thermal vacuum (TV) testing, reference file data are collected and the instrument is characterized and calibrated. The first two TV sessions took place in the winter of 2004 and spring of 2007. TV3 testing is scheduled for early spring of 2008. The links below connect to pages giving the results from the various TV campaigns.
(Up to date calibration information is located in Howard Bushouse's Calibration Plan webpage. This page contains links to the science calibration test plan, SMS spreadsheets, and other associated documentation.)
