Synopsis
Calculate the unconvolved 2D model amplitudes
Syntax
calc_source_sum2d( [reg=None,id] )
Description
The calc_source_sum2d command calculates the sum of unconvolved source 2D model amplitudes. A region filter can be supplied to restrict the area of the calculation; for information on the CIAO region filtering syntax, refer to "ahelp dmregions".
- reg - optional region string. If specified, the total sum will be calculated inside the region.
- id - the id of the dataset to use; if not given, uses the default dataset id (id=1 by default, see "ahelp get_default_id")
Example 1
sherpa> calc_source_sum2d() sherpa> calc_source_sum2d(id=2)
Calculate the unconvolved model amplitudes over the entire default dataset. Repeat the calculation for dataset id=2.
Example 2
sherpa> calc_source_sum2d("circle(25,25,10)")A region string is supplied, so the unconvolved model amplitudes for the default dataset are calculated within the circle.
