Figure 1 shows the mean V-band stellar profile (black line ) computed using the product OM images from observation 0123920101 (BPM 16274). The blue line is the computed fraction of total counts and the green one that obtained using the function CAL_omPsfEncircledEnergy, which is a subroutine in the XMM Science Analysis System (SAS) that computes the fraction of energy that is contained in a circle of a given radius centred on a source using data stored in a XMM calibration file. Note that as well as this plot, ompsfprofile produces a similar one for each image file.
The command-line to produce this plot was:
ompsfprofile directorylist=/opt/data/ssco2/odf/cycle_0081.
The default filter (V) and binning factor (2, i.e. low-resolution) were used in this case. This directory contained the procesed OM images for the observation 0081_0123920101. The same could have been accomplished by going to the directory /opt/data/ssco2/odf/cycle_0081 and simply typing ompsfprofile.
Figure 2 shows the distribution of FWHM values from a processing of over 300 observations. As in the previous example, here the default filter (V) and binning factor (2) were used as well.
