FOC Exposure Time Simulator (FOCSIM)
This FOC simulator provides information about the expected count rate and
ideal exposure time to reach a given S/N for FOC images based on the latest
calibration information. Please note that this software tool is no longer
supported by STScI.

This form has been created to assist in the
determination of image orientations. The tool not only provides numerical
