... 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. ...

. You can define a file or directory by its location in relation to your current directory . The pathname is given as / (slash) separated list of the directories on the route to the file (or directory) from your current directory. A .. (dot dot) is used to represent the directory immediately above the current directory. In all shells except the Bourne shell, the ~ (tilde) character can be used as shorthand for the full pathname to your home directory. Examples . Did You Know? .
