[Aavso-photometry] Re: [TransitSearch] preliminary results

[Pertti Pääkkönen]

Hi,

Here are my results for the HD80606-b campaign in a nutshell

2005-02-25 17:57 - 19:14 UT: V-C = -0.1456 +/- 0.0018 (overlapped with Arto's run)
2005-02-26 18:19 - 18:47 UT: V-C = -0.1460 +/- 0.0023 (just check)

Filter: V
Comp: HD80607, V = 9.07
Uncertainty is the STD of V-C curves.

Jan 25 photometry is already submitted to AAVSO.

Best regards,

Pertti
