Positional data files

This section provides downloads of the complete set of JUPOS positional records. There are two ZIP archives: First, of files with extension .MEA that include measurements (mostly of electronic images but also made with micrometers and derived from drawings in former years). Second, of files with extension .CMT that contain visual C.M. transit timings.
