It is not clear from the user guide how to do multicolor photometry. I would like to be able to do photometry in addition to V which is done very well, B, Sloan filters g', r', i'.

Can you give me some advice.
Thanks, Dick

For example, I take photometric measurements of supernovas in B, V, g', r' and i'. These are the APASS filters so I can use APASS standard stars to do photometry on the image set, typically 100 images in each color. I want to get the SN magnitude in each color for the image set and then plot the light curves.
