eimsim (eimsim-2.4.2) [xmmsas_20211130_0941-20.0.0]


Make a counts/pixel expectation-value image

This function may be performed alone by calling the script with entrystage and finalstage=`makectsimg'.

This performs the second of the three stages listed above. Essentially it just consists of multiplying each of the rate images obtained from the previous (first) stage by the appropriate exposure map. The background expectation-counts image which was made in eimsimprep is then added.
