... It uses the transformation parameters computed by the command ASTROMET/TRANSFORM . ... ASTROMET/COMPUTE computes the RA,Dec coordinates from X,Y coordinates directly from the transformation parameters, while it obtains X,Y from the RA,Dec ones in an iterative manner. Also note that the equinox of the computed coordinates is the same as the standard star catalogue (which is NOT necessarily the same as its epoch) and is 2000.0 in case the PPM catalogue is used. ...

The aim of this assignment is to teach you how to carry out a very common programming task: reading in a bunch of data from a text file, doing something with it then writing the results out again. ... The goal of the assignment is to write a computer program which will select this sample for you. You will pick the micro-quasars to observe from a rather large catalogue, which can be found here: The catalogue is an ASCII (text) file - you can inspect it with a normal text editor. ...
