Example

chips> cr = read_file("evt2.fits");
chips> trans = get_transform(cr, "MSC");
chips> data = _reshape([4000.0,4000.0,5000.0,5000.0], [2,2]);
chips> odat = apply_transform(trans, data);
chips> print(odat);
359.987 -0.0131883
0.123478 0.123478

The "MSC" transform from evt2.fits is applied to the values (4000,4000) and (5000,5000).
