Sorry for a tech question. I'm imaging SS Cyg an Vphot does not like my R for Red or B for blue. Are we supposed to use something different? I'm getting my transformations before I submit my data.
What kind of filter are you using? R for Red and B for Blue indicates that you are not using a photometric filter like Johnson B or Cousins R. Are you using your pretty picture filters (RGB) or a DSLR?
In AAVSO and VPhot terminology, these should be called TB or TR. Make Sense?
However, IF you do transform the magnitudes, you can report them as photometric B and R.
For details, you should switch to the VPhot forum.
