# SN2008aw magnitudes from Swift UVOT # generated Fri Oct 2 19:05:51 CDT 2015 using version 2015.1 # of Peter Brown's photometry pipeline # and version Swift_Rel4.2(Bld31)_25Nov2013 of HEASOFT # # Data comes from the Swift Data Center # A 5 arcsec aperture is used to measure the counts for the coincidence loss correction, # a 3 or 5 arcsec source aperture (based on the error) was used for the aperture photometry # subtracting off the galaxy count rate in a template image (if available), # and applying an aperture correction as appropriate (based on average psf in Swift CALDB) # and zeropoints from Breeveld et al. (2011) which update Poole et al. (2008) # including a time-dependent sensitivity loss # to put the magnitudes on the UVOT photometric system described in that paper. # The sensitivity correction has been updated based on the 2015 redetermination. # # Brown, P.
