Delta Cepheid - Variable Star (Cepheid)

As part of an ongoing project examining the variability in Delta Cepheid, further image sets of the variable star Delta Cepheid & the reference star SAO 34542 were recorded at around 20:45h UT.  Image sets comprised  7 sequences of  images (3 x 0.2s V & 3 x 0.6s B) alternated between Delta Cepheid & reference star.  These were analyzed using the methodology described under 2005-10-05 Notes, and combined with previous estimates from Oct 2005 and Jan 2006 .
{See also 2006-01-31 notes}

B Band Magnitude estimates for Delta Cepheid based on observations 
on 13 observing sessions between 2005-10-02 and 2006-01-31.
