componentlist.setrefdirframe - Function

1.2.1 Set the reference frame for the direction

Description

The setrefdirframe function sets the reference frame for the reference direction of the specified components (what a mouthful)!

Currently the reference frame does not include additional information like when and where the observation took place. Hence only reference frames that are independent of this information can be used. This includes the common ones of ’J2000’, ’B1950’, and ’Galactic’. The measures module contains a complete listing of all possible reference frames. The parsing of the reference frame string is case-insensitive.

Arguments


Inputs
which	A vector of indices specifying the components to modify. A vector with indices between 0 and one less than the list length, inclusively
	allowed:	int
	Default:
frame	The new reference frame, A string like ’B1950’, ’J2000’ or ’galactic’
	allowed:	string
	Default:
log	Send a message to the logger
	allowed:	bool
	Default:	true

Returns
bool

Example

cl.open(’crux.cl’);
cl.setrefdirframe(0, ’B1950’);
