[Aavso-photometry] Charts and more for TRES-1 Transit Search Object

[Pertti Pääkkönen]

Hi,

Welcome back! I was about to submit my partial TrES-1 observation, but the V-C values
are truncated to 100th of magnitude by WebObs. Usually an accuracy of 0.01 mag is
reasonable but for the TrES-1 the observable variations are order of 0.02 mag, and
my uncertainty is 0.004. I don't like that accurate photometry will be truncated in
this case (my 84 observations will then consist of 5 discrete magnitude steps only).
Shall we submit observations anyway?

Best regards,

Pertti
