ALCDEFVerify is a web-based tool that runs the same verification checks used when uploading files to the ALCDEF database. It was developed for those writing third-party programs or scripts to debug and validate their data prior to uploading the files to the ALCDEF database.

Up to three files can be processed during each run.
It is strongly recommended that each file be < 1 MB.

(see section 3 of ALCDEF standards documentation)

S-ALCDEF is for those who have basic text data files, e.g., JD, magnitude[, magerror]. Usually with a minimal amount of editing, these files can be uploaded to the ALCDEF database without creating the more detailed and rigorous standard ALCDEF files.

N.B. If using Gaia G magnitudes, you must set MAGBAND=GG (Gaia G). The single-letter 'G' can be confused with the Sloan g magband. There is no 'G' filter, so use FILTER=X, where X is one of the accepted filters.
