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?

Allocating memory for resorting the file. ----***** 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) _____________________ ERROR running VaST on the field Ori-03-Q1b1x1 (less than 4 images processed) exp_start= 09.01.2026 04:31:00.160 exp= 20.000 JD= 2461049.68831204 ap= 4.6 rotation= 0.000 *detected= 106968 *matched= 106968 status=OK /data_ssd/NMW-TexasTech/reference_imgs/Ori-03-Q1b1x1_2026-01-08_22-31-00_20.00sec_-14.90C_LIGHT_0159.fits exp_start= 09.01.2026 04:31:42.944 exp= 20.000 JD= 2461049.68880722 ap= 4.6 rotation= 0.001 *detected= 107185 *matched= 98423 status=OK /data_ssd/NMW-TexasTech/reference_imgs/Ori-03-Q1b1x1_2026-01-08_22-31-42_20.00sec_-14.90C_LIGHT_0160.fits exp_start= 28.10.2026 08:59:07.465 exp= 20.000 JD= 2461341.87450770 ap= 3.4 rotation= 85.842 *detected= 50548 *matched= 310 status=ERROR /data_ssd/NMW-TexasTech/workdir//img_2026-10-28_CI_Ori-03-Q1b1x1_040304_TTUQ1b1x1_4048641_DuJQykE8/fd_Ori-03-Q1b1x1_2026-10-28_03-59-07_20.00sec_-0.00C_LIGHTs_0448.fits exp_start= 28.10.2026 09:02:19.244 exp= 20.000 JD= 2461341.87672736 ap= 3.4 rotation= -134.478 *detected= 39889 *matched= 2172 status=ERROR /data_ssd/NMW-TexasTech/workdir//img_2026-10-28_CI_Ori-03-Q1b1x1_040304_TTUQ1b1x1_4048641_DuJQykE8/fd_Ori-03-Q1b1x1_2026-10-28_04-02-19_20.00sec_-0.00C_LIGHTs_0449.fits ########### Completed Ori-03-Q1b1x1 ########### The analysis was running at tau We are allowed to update the exclusion list at tau host Found ../exclusion_list_TTUQ1.txt #### The exclusion list before filtering-out asteroids, bad pixels and adding Gaia sources #### ################################################################################### renamed 'exclusion_list_index_html.txt_noasteroids' -> 'exclusion_list_index_html.txt' renamed 'exclusion_list_index_html.txt_nohotpixels' -> 'exclusion_list_index_html.txt' # Count candidates with no identification (that also don't look like hot pix) Found 0 unidentified candidates (excluding asteroids, hot pixels and known variable stars). ################################################################################### 0 candidates found (excluding asteroids and hot pixels) This does not look like a test run ################################################################################### exclusion_list_gaiadr2.txt NOT FOUND exclusion_list_apass.txt NOT FOUND IS_THIS_TEST_RUN=NO ALLOW_EXCLUSION_LIST_UPDATE= YES #### Nothing to add to the exclusion list #### The observatory MPC code is V36 ############################################################ ls: cannot access 'planets.txt': No such file or directory ############################################################ Positions of selected moons from JPL HORIZONS for JD(UT): ls: cannot access 'moons.txt': No such file or directory ############################################################ Positions of selected spacecraft from JPL HORIZONS for JD(UT): ls: cannot access 'spacecraft.txt': No such file or directory ############################################################ ls: cannot access 'comets.txt': No such file or directory ############################################################ List of recent ASAS-SN transients from https://www.astronomy.ohio-state.edu/asassn/transients.html : ls: cannot access 'asassn_transients_list.txt': No such file or directory ############################################################ Truncated list of TOCP transients from http://www.cbat.eps.harvard.edu/unconf/tocp.html : ls: cannot access 'tocp_transients_list.txt': No such file or directory
