(Mandatory) A source timeseries dataset created by evselect. The header must contain the following keywords:
INSTRUME - either `EMOS1', `EMOS2' or `EPN'
The dataset must contain a binary table extension named RATE which must contain the following keywords:
E_MIN, E_MAX - energy interval of the TS
E_UNITS - units of the previous, either `eV' or `keV'
TIMEUNIT - eg `s'
MJDREF
The RATE extension must contain a column COUNTS, which may be of integer type int16 or int32 (FITS data types I or J). If it contains no TIME column then it must contain a TIMEDEL keyword and an intelligible subset of TIMEZERI, TIMEZERF and TIMEZERO. Selection region and GTI information must be stored in a data subspace (DSS) of this RATE extension. If there is no DSS, the selection region will be assumed to occupy the entire surface of the camera and the whole duration of the TS will be assumed to fall within GTI.
(Optional) A background timeseries dataset, also created by evselect. If it is supplied it must have the same specifications as the source TS, and the values of the mandatory keywords must be the same.
(Mandatory) A calibrated event list for the relevant MOS camera, created by either emchain
or epchain. The header must contain the following keywords:
INSTRUME - must be the same value as the TS one.
FILTER
The event list must contain the binary table extension EVENTS, which must contain the following keywords:
TIMEUNIT - must be the same value as the TS one.
MJDREF - must be the same value as the TS one.
The event list must contain at least one binary table extension EXPOSUnn, where nn indicates the ccd/node. Each of these extensions must contain the following keywords:
WINDOWX0
WINDOWY0
WINDOWDX
WINDOWDY
Any other keywords needed to set the state of the cal via a call to CAL_setState.
an intelligible subset of TIMEZERI, TIMEZERF and TIMEZERO
The EXPOSUnn extensions need not contain any columns, but correct exposure calculations cannot be performed unless each relevant extension (ie, each one corresponding to a ccd within the collection region) contains the following columns:
FRACEXP - real32.
TIMEDEL - real32.
TIME - real64.
If the event list contains BADPIXnn extensions (not mandatory), these must contain the following columns:
