All-image limiting magnitude estimate: 14.4 (SNR ) 11.3 (80% of stars) with default.sex.telephoto_lens_onlybrightstars_v1
The first estimate is the magnitude of a star detected with a signal-to-noise ratio of following Karpov (2025, Acta Polytechnica, 65, 50).
This value should be representative of the faintest stars clearly visible in the image.
The brighter of the limiting magnitude estimates for the two second-epoch images is reported here.
The second estimate is the 80th percentile of the magnitude distribution of stars detected on all four images.
This value is representative of the faintest object that may enter the candidate transients list.
The hard cut-off for the candidate transients is 15.5 mag.

Excluding outliers - 4835 stars left (next iteration limit 5317)
Stop iterations.
The field is successfully solved and matched with the astrometric catalog! :)
SIP_REFIT: wcs_fd_Mon-02-Q2b1x1_2026-10-06_02-59-37_20.00sec_-0.00C_LIGHT_0400.fits is a symbolic link - will not rewrite the WCS of whatever it points to, but will still refit the output catalog positions

The minor axis of the CCD chip should be 24.0 mm based on the derived pixel size of 3.8 um
Internal estimated FoV 605.3'
The guess is based on the FOCALLEN keyword.
