Foreword

This report follows daily changes in local ITF files. In this context, the ITF material is handled as fixed-width OBS80 observation records: only 80-column lines are read, the observatory code is taken from columns 78-80, and the code is accepted only when it is present in the official MPC observatory-code list or explicitly approved as a local special case.

Daily ITF changes are useful in two directions. The submission-date view answers when a line entered or left the daily files. The observation-date view answers when the underlying observation was made, using the first chronological snapshot as the initial added data and then applying all later added and removed files.

Station names and code validation come from the MPC observatory-code list at ObsCodes.html. The station code in the tables links to the local station page. Code XXX is treated as the approved local special case.

The left navigation opens the report pages: this foreword, By submission date, By observation date, Station checks, separate UTFS table pages, and Data files.
