Michael,

OK, here is what I have:

196288   6 103.5562 7.9414 2452609.85861 V 11.343 0.022   0 I 10.599 0.010   0
196288   6 103.5562 7.9408 2452615.84229 V 11.414 0.036   0 I 10.625 0.014   0
196288   6 103.5563 7.9415 2452619.83174 V 11.208 0.021   0 I 10.530 0.010   0
196288   6 103.5566 7.9412 2452616.83959 V 11.328 0.022   0 I 10.597 0.010   0
196288   6 103.5568 7.9413 2452614.84494 V 11.551 0.033   0 I 10.723 0.013   0
196288   6 103.5571 7.9407 2452612.85042 V 11.244 0.083   0 I 10.444 0.039   0

Note that this data was taken with the star in the same position in the 
frame each day, so it should not be subject to the calibration errors that 
we have been discussing.  Not that there is an absolute calibration, just 
that the measurement was taken under the same conditions each night.

Hope this is useful,

Tom
