Source Catalog
Met again this week. Jean presented results from a new look at the test pattern data sets with likelihood analysis. One interesting result was the flux limit as a function of source spectral index. He also updated his comparison of source detection algorithms on obssim2 data, drawing interesting conclusions from studying which sources were detected by only one of the algorithms. Jean also investigated the effect of removing sources below the detection threshold in the 'time' part of the pipeline analysis. This is fairly closely analagous to what is done for source monitoring in ASP. He found that the effects on the measured fluxes for the remaining sources were typically very small. He did not measure the CPU time but by halving the number of sources the expectation is that the CPU time required decreased by a factor of 4.
