I download the fits images of MisV1147 from the USNO server http://vsnet.nofs.navy.mil/data/fchpix/cfra.html and reduced the images using MIRA software. I used the comparison stars from Mike Simonsen's chart at http://joevp.20m.com/cgi-bin/i/charts/henden/And%20to%20Gem/Cep_MisV1147_C_reverse.gif . This chart is based on Arne Henden's photometry. Stars labeled 135 and 138 were used as comparison stars and star labeled 132 was the check star. The magnitudes taken directly from the USNO-B file are for comparison. The typical errors for USNO-B are 0.25 mag. The average residual between the two comparison stars is approximately 0.15 mag.
