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 15.0 mag.

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.
