General Description

• Aim: To obtain MOS spectra (300V) of Ultraluminous X-ray sources (ULXs)
   in the fields of nearby galaxies.
  
  Targets: lie in the fields of two galaxies -- NGC5774/5775 and NGC3256. The first
   one (NGC57745) is observed twice and the second one (NGC3256) is observed three
   times, in order to get a slightly different set of ULXs between OBs, and to obtain
   twice the exposure time on some fainter targets. Two other galaxies that we proposed
   to observe in phase 1 are not observed due to recent published result from another
   group.
           The ULXs themselves are faint, and bright spectra may not be visible in
   the individual exposures, though a couple of slits have been placed on brighter
   stars for slit monitoring.
  
  Acquisition: Is done in the B filter, since there were issues concerning slight
   offsets produced by the V_BESS filter during MOS observations in the past. If this
   no longer applies, please change acq filter to V_BESS.
  
  Finding Charts: For each of the two galaxies, the first chart shows a large field,
   and a second chart shows a zoom-in. Astrometry has been confirmed with SDSS/HST/FORS1.
   In one or two cases, the full FORS MOS field is not shown, but the field, orientation
   etc. should be obvious with the shown field of several arcmin.
