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. ...
