Transformation coefficients have been added for SRO50, BSM, W28 and W30, which allows you to transform B and V images using one of the two methods available in VPHOT.
You must be a mind reader. I was just chatting with Arne online last night about this very feature!! Amazing.
Keep up the great work, Geir.
For SRO50 we're getting images in UBV. When using VPHOT it appears there are only "known" coefficients for B-V, but not for B-U or V-U. Do we have the coefficients for the U filter for SRO50? Can they be added to VPHOT?
