eupper (especget-1.54) [xmmsas_20211130_0941-20.0.0]

Find an upper limit using an annular background region

eupper imageset=imagepnew.ds srcra=187.912 srcdec=64.2 srcradius=0.00833 bgdra=187.912 bgddec=64.2 bgdrinner=0.01666 bgdrouter=0.03333

This will find the upper limit from a 30 arcsecond circle about the sky position, ra=187.912 degs, dec=64.2 degs, using a background annulus about the source circle of inner radius, 1 and outer radius 2 arcminutes. The exposure time will be taken from the primary header of the file imagepnew.ds and the result will be a 2-sigma upper limit.
