[Aavso-photometry] Determination and use of BVRI

 Lionel, Trying to write equations as plain text files is awkward and good
ol' Outlook didn't help any by removing some of returns between equations
during spell check. 

I saw in the notice for the new AAVSO observation file formats that Maxim DL
will be supporting them. That may make it easier to get the info out of
Maxim that you need to apply transformation coefficients since they want the
measured values of the comp star. At least you should be able to back the
zero point out of your target star measurements without manually recording
the data from the information dialog window.
