Timing Analysis without the deconvolution

During the run of stand alone programevts_extract two data structures GNRL-EVTS-GTI and GNRL-EVTS-LST are filled.

GNRL-EVTS-LST (Table [*]) combines all available information for photon-by-photon events from different instruments during a given time interval.

Table: Content of the GNRL-EVTS-LST Data Structure.
Column Name Description
DETY Y location in the detector layer (offset from center)
DETZ Z location in the detector layer (offset from center)
ENERGY Energy deposited by the event
EVNT_TYPE Type and origin of event (bit coded)
TIME Time of event in INTEGRAL Julian Date units
TIMEDEL Uncertainty of time stamp
DEADC Dead time correction factor
BARYTIME_N Barycenter time for source number N
PIF_N Pixel Illumination Factor for source number N
AREASCAL_N Nominal effective area for source number N

GNRL-EVTS-GTI (Table [*]) contains good time intervals for selecting events.

Table: Content of the GNRL-EVTS-GTI Data Structure.
Column Name Description
START IJD of start of the GTI
STOP IJD of end of the GTI
OBT_START On-board time of start of the GTI
OBT_END On-board time of end of the GTI
UTC_START UTC of start of the GTI
UTC_END UTC of end of the GTI
