General Description

This is program to investigate the Ly-alpha emission surrounding a set
 of QSOs at approximately the same redshift to compare their halos with those of
 the quasars.  Do QSOs generate outflows like the radio loud AGN do?  Some of the
 IFUs point at QSOs while others point at stars to be used a PSF references.  The
 program requires 10 hours to telescope time and we asked for and were granted a
 waiver to exceed one hour per OB.  We asked for 1h 40 minutes, but finally
decided on a more modest 1 hour and 15 minutes.  The objects are faint, about 19
 magnitude or less and so they shouldn't be visible in single exposures.  The PSF
 stars on the other hand can be much brighter and should be visible in a single exposure.
  We have not therefore listed an "expected" S/N.

Waiver Requests
