Re: date error, alleged

Chris,

No, the link (at least for me) between a datapoint and an image is the JD.

In the Mjra3096550.cal (TOM3 for 2453096.550) file of observations I get:
   0   71.99474   86.64520 2453096.55032    V 11.678  0.013 0         I 11.123  0.006 0

And in Mjra3096550.list (list of images processed into Mjra3096550.cal) I get:
jira3096550.fits I 2453096.55035 90.4 object 116.61 +85.57 7651 67.12 2.52 4199 -8.262 0.060 1
jvra3096550.fits V 2453096.55032 90.5 object 116.59 +85.66 3801 64.27 2.63 1780 -9.034 -0.063 1
