Instrumental Magnitudes and Colours

The tabulated magnitudes are those that have been computed by ommag- as mentioned in the previous section, omsrclistcomb will have averaged all the magnitudes from sources that it considers to be the same. Omsrclistcomb uses a colour table that it loops through to see if the relevant instrumental magnitudes (one of U, B, V, UVW2, UVW1, UVW2 and UVM2) are present for the calculation of the instrumental colour. The colour list is :-U-B, B-V, U-V, UVW2-UVW1, UVW2-UVM2, UVM2-UVW1, UVW2-U, UVW2-B, UVM2-U, UVM2-B, UVM2-V, UVW1-U, UVW1-B, UVW1-V
