componentlist.sort - Function

1.4.2 Sort the components in a list
Description

The sort function can sort all the components in a list using a variety of criteria. Currently the following criteria are available.

Flux: Sorts the list so that the brightest components, as defined by the abs(I), are at the beginning of the list.
Position: Sorts the list so that components that are closest to a reference position, which is currently fixed at (ra,dec) = (0,0), are at the beginning of the list.
Polarization: Sorts the list so that components with the largest fractional polarization, , are at the front of the list. Components where I = 0 are placed at the end of the list.

The parsing of the string containg the sorting criteria is case insensitive. You cannot sort a list that has been opened read only.
