The MeqLMRaDec node converts a coordinate at a given L, M location (in radians) with respect to the field centre into a corresponding RA and DEC . The node uses the aips++ DirectionCoordinate class to perform this conversion. The node requires two children - the first is a MeqComposer node containing the RA and DEC values of the field centre, and the second is a MeqComposer containing the L and M coordinates of the position that is to be converted.
