Overview
WFC3 Calibration Plan
Initial calibration of WFC3 has taken place on the ground in simulated orbital conditions. Shortly after launch, observations were used to assess the on-orbit performance of the camera during a period called Servicing Mission Orbital Verification (SMOV). As with the other HST instruments, calibrations will be periodically updated through new observations campaigns every year.
Every cycle, the WFC3 team executes a routine set of monitoring programs for the UVIS and IR detectors. This plan is designed to:
- 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, flux and wavelength stability of the grisms
- Maintain and update the standard reference files
- biases, darks, linearity, CTE traps, UVIS anomalous QE pixels, post-flash, flats, photometric calibration
- Support new initiatives and obtain supplemental (non-routine) calibration data to investigate any changes
The results of these calibration programs are documented as they become available via Instrument Science Reports on the WFC3 ISR webpage.

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 were collected and the instrument was characterized and calibrated. The first two TV sessions took place in the winter of 2004 and spring of 2007, and TV3 testing took place in spring of 2008. The links below connect to pages giving the results from the various TV campaigns.
(Additional calibration information is available on the Calibration Plan internal webpage by Bushouse. This page contains links to the science calibration test plan, SMS spreadsheets, and other associated documentation.)
