Tool simulator


Set start, stop, gap, integration times


Synopsis
settimes(integrationtime, gaptime, usehourangle, starttime, stoptime, referencetime)



Description
Set various times for the simulation, including start, stop, integration, and gap times. The start and stop times are referenced to referencetime. Use either starttime/stoptime or startha/stopha. If the hour angles are specified, then the start and stop times are calculated such that the start time is later than the reference time, but less than one day later. The hour angles refer to the first source observed.



Arguments

integrationtime Integration time
Allowed: Quantity
Default: '10s'
gaptime Gap time between observations
Allowed: Quantity
Default: '20s'
usehourangle Use starttime/stoptime as hour angles - else they are referenced to referencetime
Allowed: Bool
Default: T
starttime Start time referenced to referenceepoch
Allowed: Quantity
Default: '0s'
stoptime Stop time referenced to referenceepoch
Allowed: Quantity
Default: '3600s'
referencetime Reference time for starttime and stoptime
Allowed: Epoch
Default: '50000d'



Example
  reftime := dm.epoch('utc', 'today');
  mysim.settimes( integrationtime='10s', gaptime='0s', usehourangle=T,
                starttime='0s', stoptime='3600s', 
                referencetime=reftime);
Here we use the Measures tool to define today's epoch which we use in settimes. Here we set a 3600 s observation after the reference time with 10 s of integration and no gap between integrations.
