I got stuck running the multiplot-aperture measurements process on 445 calibrated FITS images which include a
meridian flip shortly before the predicted egress of exoplanet TrES-3b. I have tried to follow the method described in section 7.5.4 of the
Practical Guide (revision 3.1) having plate-solved two images. The first image overall and the first image after the flip using (remote) Astrometry.net. I have also marked the checkbox "Use RA/Dec to locate aperture positions" on the relevant screen.
However, the differential photometry process does not proceed through all pre-flip images using the coordinates of the first plate-solved images. Ditto for the images after the flip. Here's an example message:
***ERROR: WCS mode requested but no valid WCS FITS Headers found in image 2018-06-10_GSC 3089_929_Light_15.000secs_3x3_EBB_-3.99C_00003379_out.fit. Skipping slice 2.
I am running AIJ 3.2.0 using in-built Java 1.7.0_71 (64-bit) on a Windows10 HP notebook.
I havn't found an explanation on this board and much appreciate your help.
Cheers
