MODIFY POSITION
LAS\MODIFY POSITION Lambda Beta
Change the projection center to (lambda_0,beta_0). The offsets are also
modified, as to be consistent with the center. This command is usefull
when different parts of one source are mapped relative to several refer-
ence positions. Only RADIO projection is supported.
If the coordinate system is EQuatorial:
lambda = lambda_0 x 12 /pi
beta = beta_0 x 180/pi
If the coordinate system is GALactic:
lambda = lambda_0 x 180/pi
beta = beta_0 x 180/pi
