I should begin with the disclaimer that I am for the most part, a spectroscopist... But I have been dabbling with some Stromgren Photometry of late. Working through the process with the noao.digiphot routines, all goes well until the inverting of my instrumental magnitudes. The results appear sane, but no errors are calculated - the error columns all have INDEF values, despite errors being set to "obserrors" in the parameter file.I'll be the first to admit I've likely messed something up, but darned if I can find it. For the curious, my config file, parameters file, and observations file have been tarred up and can be downloaded from:http://www.phys.uwosh.edu/mike/photfiles.tar (117K)Any help would be appreciated.
