Parallel Observations

The Faint Object Spectrograph was used to observe a blank region of sky in parallel with the WFPC during most of the HDF. Half the time was spent obtaining spectra to calibrate the HST scattered-light model. Larry Petro will be analyzing these data. The other half the time was spent obtaining spectra to use as a calibration for a measurement of the extragalactic background light. These data are proprietary to Wendy Freedman and collaborators.
