Polarized quantities

Synopsis
pol(which, debias, clip, sigma, outfile)

Arguments

which	in	Specify operation
		Allowed:	String: One of 'lpi', 'tpi', 'lppa', 'flp', 'ftp' (case insensitive)
debias	in	Debias the polarized intensity ?
		Allowed:	T or F
		Default:	F
clip	in	Clip level for auto-sigma determination
		Allowed:	Float
		Default:	10
sigma	in	Standard deviation of thermal noise
		Allowed:	Float
		Default:	Auto determined
outfile	in	Output image file name
		Allowed:	String
		Default:	Unset

Returns
Image tool or fail

Description

This function just packages the other specific polarization functions into one where you specify an operation with the argument which (can be useful for scripts). This argument can take the values:

• 'lpi' - linearly polarized intensity (function linpolint)

• 'tpi' - total polarized intensity (function totpolint)

• 'lppa' linearly polarized position angle (function linpolposang)

• 'flp' - fractional linear polarization (function fraclinpol)

• 'ftp' - fractional total polarized intensity (function fractotpol)

Example

- p := imagepol('stokes.cube')
- lpi := p.pol('lpi')
