[vsnet-chat 440] Re: SS Cyg: comparison between sequences

[bas@lowell.Lowell.Edu (Brian Skiff)]

     I think the discrepancies in the SS Cyg field among the published UBV
photometry and Tycho results from both particularly crummy work in this
field by the ground-based observers, and also the rather large errors in
the fainter Tycho stars.  I looks like the Lenouvel & Daguillon sequence
is probably most nearly correct, but the field should be observed again
to clear up the inconsistencies.
     For Kato-san:  for future comparisons, it would be useful to include
the Tycho errors for each star in the same way I have done with my results
(put the end-figures of the errors on the second line of each entry, 
something like:

   V    B-V

 9.35  0.35
  .03   .03

10.41  1.14
  .15   .20

  ....etc.
