componentlist.setrefdir - Function

1.2.1 Set the reference direction


Description

The setrefdir function sets the reference direction of the specified components to a new value. The direction is defined by separately specifying the right ascension and the declination.

The right ascension is specified as a string or a real number

Ra can be in standard angle units ’deg’, ’rad’, or time formatted as such ’HH:MM:SS.sss’ eg., ’19:34:63.8’ or angle formatted as such ’+DDD.MM.SS.sss’ eg., ’127.23.12.37’.

Similarly the declination is specified as a string or a real number and the decunit can be any angular unit or ’angle’ or ’time’.
