Message:

do not crash psphot if variance is not supplied; include mask and mark in modelGuess functions (needed for trail angle guess); fix Reff sx,sy,sxx relationships; define new function to measure guess at the trail angle; tell pmSourceIO if MATCHED_REFS have been read (& skip); do not read sources for WCS type
