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
