Maps - FITS format - MJy/sr units

Maps - Matab format - MJy/sr units

Images are stored as matlab structures called 'map'. The structure has length 2, one for each frequency, and each frequency has 'T', 'Q' and 'U' maps, corresponding to Stokes I, Q and U parameters in each map pixel. A corresponding structure 'm' contains the axes information; m.x_tic gives the RA coordinates, m.y_tic gives the dec coordinates.

To look at the 150 GHz T map, in matlab do:
>> imagesc(m.x_tic,m.y_tic,map(2).T).

For the 100 GHz U map, do:
>> imagesc(m.x_tic,m.y_tic,map(1).U).
