The RTS source list format
Coordinates are right ascension and declination, which have units of decimal hours (i.e. 0 - 24) and degrees, respectively. All frequencies are in Hz, and all flux densities are in Jy.
Gaussian and shapelet sizes are specified in arcminutes, whereas position angles are in degrees. In an image space where RA increases from right to left (i.e. bigger RA values are on the left), position angles rotate counter clockwise. A position angle of 0 has the major axis aligned with the declination axis.
All flux densities are specified in the "list" style (i.e. power laws and curved power laws are not supported).
Keywords like SOURCE, COMPONENT, POINT etc. must be at the start of a line
(i.e. no preceding space).
RTS sources always have a "base source", which can be thought of as a non-optional component or the first component in a collection of components.
