... The choice of exposure time generally depends on the signal-to-noise ratio required to meet the science goals. ... See "Overhead Times" on page 29 for more information about exposure timings.) ... For example, shortening an exposure from 400s to 350s has no effect on orbit packing; they both require 9 minutes to execute ( CLOCKS=NO, the default setting). On the other hand, shortening an exposure from 180s to 160s trims the execution time by 2 minutes (again CLOCKS=NO, the default setting). ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

... Timer functions can be used to time operations (e.g., to see how much time has elapsed). ... You can then use g_timer_start() to start timing an operation, g_timer_stop() to stop timing an operation, and g_timer_elapsed() to determine the elapsed time. GTimer *g_timer_new( void ); void g_timer_destroy( GTimer *timer ); void g_timer_start( GTimer *timer ); void g_timer_stop( GTimer *timer ); void g_timer_reset( GTimer *timer ); gdouble g_timer_elapsed( GTimer *timer, gulong *microseconds ); . ...

... Again to facilitate comparison of time series, the same start and stop times are used for all EPIC source time series from a given observation. These times are obtained from TSTART and TSTOP keywords in the EVENTS table headers of the PN, M1 and M2 event lists. The start time is taken as the minimum of the TSTART values and the stop time as the maximum of the TSTOP values. These values are then written as TLMIN and TLMAX keywords to the TIME column of all the input event tables. ...
