Efficient use of the WFPC2 requires an understanding of the overhead times of the instrument. ... The start of an alignment requires 1 minute overhead in order to synchronize timing with a major frame (all commands to the instrument take place on major frames which last 1 minute). ... If scans are being performed, another minute of overhead is required and, if images are requested in real-time, another 2 minutes must be added to the alignment end. ... The readout time for an exposure is one minute. ...

. Accurate flux calibration is required to derive to many intrinsic properties of the galaxy like star formation rate. It is also required to compare the data from different instruments. In this FoF I will summarise some of the issues (and hopefully their solutions) encountered while flux calibrating data from DEIMOS spectrograph on KECK.
