Questions

Observing_Description:
The observation will begin with a two stage target acquisition (binary search and peakup)
designed to center the object to 0.08" accuracy.  This accuracy is required because the
signal-to-noise of the spectrum calls for moderately accurate flat fielding.  Following
this a 2860 second observation with the G270H grating and 0.5" aperture will be
performed.  Accurate wavelength calibration is not required because several strong
interstellar lines will be present in the spectrum.

Abstract:
This proposal contains observations which will help to complete an FOS IDT scientific
program.  This data set will yield high quality absorption line data for studies of the
damped Lyman alpha absorption system at z=1.0 and the Lyman alpha forest lines for an
independent sample for studies of absorption line evolution.
