Since I am no longer doning photomery and concentrating on spectroscopy I am posting this to the photometry forum in hopes someonce can help. I recieved the following question.
I have a question pertaining to selecting transformation stars. I know different spectral types should be chosen and that they must not be variable stars. But it is hard to find stars that are included in Cousins database that are not double stars. I noticed that Jerry Persha used some double stars in his sample transformation star database. Is this ok?
Anyone have suggestions or comments? Thanks!
