Source list

Source positions are read from the input source list file which has to contain celestial coordinates (RA, DEC), EPIC-pn or EPIC-mos1/2 counts (PN_CTS or M1_CTS or M2_CTS) and EPIC-pn or EPIC-mos1/2 offaxis information (PN_OFFAX or M1_OFFAX or M2_OFFAX). This is the default method.

Table 3: Input Source List. Mandatory Columns (case 1)

Src number	Right-ascension	Declination	PN counts	PN Off Axis	M1 counts	M1 Off Axis	M2 counts	M2 Off Axis
SRC_NUM	RA	DEC	PN_CTS	PN_OFFAX	M1_CTS	M1_OFFAX	M2_CTS	M2_OFFAX

Alternatively the extraction region radius for each source can be present in the input source list as SRC_RAD.

Table 4: Input Source List. Mandatory Columns (case 2)

Src number	Right-ascension	Declination	Source extraction radius
SRC_NUM	RA	DEC	SRC_RAD

The resulting Background information will be added to the input Source List in extra columns. (see Section 3.2 for information about those extra columns).
