[Aavso-photometry] UBVRI photometry for RS Oph field

[Robert J. Modic]

Thanks Aaron.  What method did you use to calculate errors for
the magnitudes (other than V)?  The errors that Arne includes in
the .dat files are for color indices and trying to reverse calculate
errors for individual bands can be tricky.  For example, some stars
have a smaller error for B-V than for V.

I notice a column of "99.999".  Is this for V-I?

 I have posted Arne's UBVRcIc photometry of the RS Oph field to this URL:

ftp://ftp.aavso.org/public/calib/rsoph.dat

 I also wrote a perl script to convert it into a more human readable format.  
For now use it at your own risk.  I'm interested in any comparison of its output
with similar scripts anyone else has written. It is located here:

ftp://ftp.aavso.org/public/calib/rsoph.txt

 By the way, that's the new FTP site of Arne's .dat files. So update your 
bookmarks and use it for future .dat downloads.
