TASS CD 23 and loneos.phot
Brian Skiff's loneos.phot file is a critical compendium of
Johnson-Cousins BVRI photometry (quite a bit of which is sourced from
Arne's data I think). Though that doesn't make it a primary or
secondary photometric standard, it is always something useful and to
hand with which to make comparisons against other photometry sets,
especially as it is nowadays quite large and covers a great deal of sky,
allowing chance of matches.
There aren't enough matches from the TASS CD 23 and loneos.phot sets to
warrant any graphing, so I'll just list up the 47 matches at a 2.5"
radius cross-check.
Headings are more or less self explanatory (TASS ID is collected.big
running number), the TASS CD 23 data and the loneos.phot data are
separated midtable by columns of deltaVJ (TASS VJ - LONEOS VJ) and
deltaVJ-Ic (TASS VJ-Ic - LONEOS VJ-Ic). Note that I'm pretty sure Brian
uses Ic, it being a Johnson-Cousins dataset, and does not use IJ, but I
could have missed a point somewhere.
Data attached, hopefully "inline" to the email.
Cheers

[PS haven't done all this sort of thing for a while and have made a bit
of a gaff with the positional testing on some things such that earlier
reports re xray sources or twins are not incorrect but are likely to be
a _subset_ of the true number of matches. Sorted that now, so this
loneos match should be complete. Xray sources, PG objects and some
other stuff will be re-assessed in time, but the CV check should be
complete as I did that by "eye", it being quicker to do that for this
narrow band of sky than convert the online D&S data into a processable
form]
