... A full set of flatfield frames was taken with the NICMOS arrays during the System Level Thermal Vacuum test, conducted on the ground in August 1996. ... Users are encouraged to recalibrate their data with on-orbit flatfields if the pipeline calibration used thermal vacuum flatfields. Preliminary results from SMOV indicate that variations in the large scale structure of the on-orbit flatfields relative to the thermal vacuum flatfields are of the order of 1-2% in Camera 2, and up to 5% in Camera 1. ...
