Þ On multiple machines, issue the command : cl < reduce.cl >& reduce_machinename.log & where reduce.cl = CL script created by GSCRIPTER reduce_machinename.log = logfile for machinename No limit on number of processors simultaneously crunching through the same list of objects. This is fun. Creating Residual Images with GRESIDUAL Þ IRAF Parameters : in_image = "gssf9w3t" Name of input image res_image = "gssf9w3t_res" Name of output residual image imlist = "@olist" List of model thumbnail images (mode = "q") Post-Processing of Output Logfiles Þ Perl scripts are very useful ! Þ Full Monte-Carlo propagation of errors. Example: Given P(I814|D, M) and P(V606|D, M) from logfiles , Monte-Carlo sample these distributions N times, and compute V606 - I814 each time. Then compute median value of V606 - I814 and confidence intervals Comparison with Medium Deep Survey GSS catalog
