Please see the
setrefdirframe
function for a description of what frames are allowed.
Convert the reference direction to a new frame
Synopsis
convertrefdir(which, frame)
Description
The convertrefdir function changes the specified components to use a
new direction reference frame. Using this function will change the
right-ascension and declination of the component(s), unlike the
setrefdirframe which does not.
Arguments
which
A vector of indices specifying the components to modify
Allowed:
A vector with indices between 1 and the list length
Default:
no default
frame
The new reference frame
Allowed:
A string like 'B1950', 'J2000' or 'galactic'
Default:
no default
Returns
nothing
Example
include 'componentlist.g'
cl := componentlist('crux.cl');
cl.convertrefdirframe(cl.indices(), 'J2000');
This example illustrates what you would do if you had a list where
all the directions were in the B1950 reference frame but you
needed the coordinates in the J2000 reference frame. Unlike the
setrefdirframe
function this one adjusts the right ascension and declination values.
