imager.sensitivity - Function

2.3.1 Calculate rms sensitivity
Description

Calculate the point source sensitivity for the selected data, both absolutely and relatively (to that for natural weighting).

To do the calculation, we use the imaging weights (in the column called IMAGING_WEIGHT) and the specified sigma per point (in the column SIGMA). Therefore, this includes all the effects of weight and filter.

Arguments


Outputs
pointsource	Calculated point source sensitivity (Jy/beam)
	allowed:	record
	Default:
relative	Calculated relative sensitivity
	allowed:	double
	Default:
sumweights	Calculated sum of weights
	allowed:	double
	Default:
Inputs
async	Run asynchronously in the background
	allowed:	bool
	Default:	false

Returns
bool

Example

a=im.sensitivity(false)
print ’Sensitivity = ’, a[’pointsource’]
print ’Relative to Natural Weighting = ’, a[’relative’]

[next] [prev] [prev-tail] [front] [up]
