Parameter Explanations

imagename

''

Name(s) of the input image(s). Must be specified.

rm

''

Output rotation measure image name. If not specified, no image is written.

rmerr

''

Output rotation measure error image name. If not specified, no image is written.

pa0

''

Output position angle (degrees) at zero wavelength image name. If not specified, no image is written.

pa0err

''

Output position angle (degrees) at zero wavelength error image name. If not specified, no image is written.

nturns

''

Output number of turns image name. If not specified, no image is written.

chisq

''

Output reduced chi squared image name. If not specified, no image is written.

sigma

float(-1)

Estimate of the thermal noise. A value less than 0 means auto estimate.

rmfg

float(0.0)

Foreground rotation measure in rad/m/m to subtract.

rmmax

float(0.0)

Maximum rotation measure in rad/m/m for which to solve. IMPORTANT TO SPECIFY.

maxpaerr

float(1e30)

Maximum input position angle error in degrees to allow in solution determination.
