[vsnet-chat 4373] Re Confirmation and Reporting Observations

[Roger Pickard <rdp@star.ukc.ac.uk>]

I should have commented on this chat before now, but here goes anyway.
The BAA VSS also has a large database of observations of nearly 2 million 
observations (albeit not as large as the AAVSO's) with observations of a 
few stars stretching back over 100 years.
We also exchange data with the AAVSO and the RASNZ (the latter mostly of 
southern stars).
ALL VSS observations for many years have included the full estimate in 
the reporting log.   This means that if a comparison star's magnitude is 
found to be grossly in error (or even variable!) it is possible to 
recalculate the deduced magnitude using the correct value.   This also 
allows observations to be checked for any arithmetical errors etc.  
Also, as Taichi Kato pointed out, most VS organisations (all?) are using 
the standard Johnson V system for their comparison star sequences 
nowadays, and this, of course, includes the BAA VSS.
