imagepol.pol - Function

1.1.4 Polarized quantities

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)

Arguments


Inputs
which	Specify operation. One of ’lpi’, ’tpi’, ’lppa’, ’flp’, ’ftp’ (case insensitive)
	allowed:	string
	Default:
debias	Debias the polarized intensity ?
	allowed:	bool
	Default:	false
clip	Clip level for auto-sigma determination
	allowed:	double
	Default:	10.0
sigma	Standard deviation of thermal noise. Default is auto determined.
	allowed:	double
	Default:	-1
outfile	Output image file name. Default is unset.
	allowed:	string
	Default:

Returns
image

Example

"""
#
print "\t----\t pol Ex 1 \t----"
po.open(’stokes.image’)
lpi = po.pol(’lpi’)
lpi.statistics()
lpi.done()
