2.3.1.0 imager.sensitivity

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	Jy/beam	Calculated point source sensitivity (Jy/beam)
		allowed:	doubleJy/beam
		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]
