All-image limiting magnitude estimate:  13.3 (SNR )  11.0 (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.

----***** VaST processing WARNING *****----
You asked VaST to process 4 images, but only 1 were actually matched to the reference one.
Please investigate this!



**************************************************************
This error might be a bug, but it is far more likely that it is caused by 
inappropriate input data. A few simple things to check in the diagnostic
messages printed above (or the vast*.log files):
 * How many of the input images are matched?
 * Does the number of detected stars on each image look reasonable?
 * Do images have a sufficient overlap of at least about 20 percent?

You may run
 ./sextract_single_image /path/to/my/image/file.fit
to see how well VaST detects stars with the current SExtractor settings
(star detection settings can be changed in the default.sex configuration
file, see various examples in the VaST directory).

If you cannot identify the problem, please e-mail Kirill Sokolovsky 
Please try to describe the problem in details and, if possible, attach vast_summary.log
file and a few example images. If the images are too big to be sent by e-mail, please 
upload them through a web-form http://scan.sai.msu.ru/upload/
**************************************************************

Low percentage of matched images - we'll declare this an unsuccessful VaST run (exit code 1)
