imagepol.totpolint - Function

1.1.4 Total polarized intensity
Description

This function returns the total polarized intensity; ∘ (Q2 +-U-2 +-V-2) . If your image contains only Q and U, or only V, then just those components contribute to the total polarized intensity.

You may optionally debias the polarized intensity. This requires the standard deviation of the thermal noise. You can either supply it if you know it, or it will be worked out for you with outliers from the mean clipped at the specified level.

Arguments


Inputs
debias	Debias the total polarized intensity ?
	allowed:	bool
	Default:	false
clip	Clip level for auto-sigma determination
	allowed:	double
	Default:	10.0
sigma	Standard deviation of thermal noised. Default is auto determined.
	allowed:	double
	Default:	-1
outfile	Output image file name. Default is unset.
	allowed:	string
	Default:

Returns
casaimage
