. Next: Spectral types Up: Optional stellar data Previous: Optional stellar data . Proper-motion information requires three columns: the separate components, and the epoch of the catalog position. We follow the SAO Catalog in using annual proper-motion units of seconds of time per year in R.A., and seconds of arc per year in Dec. The epoch is given in decimal years. The respective column labels are MUALPHA, MUDELTA, and EPOCH. These are all Real*4 data. Pascal Ballester . Tue Mar 28 16:52:29 MET DST 1995

Some radio clocks and related timekeeping gear have a pulse-per- second (PPS) signal that can be used to discipline the local clock oscillator to a high degree of precision, typically to the order less than 50 us in time and 0.1 PPM in frequency. ... Either way requires conversion of the PPS signal, usually at TTL levels, to RS232 levels, which can be done using a circuit such as described in the Gadget Box PPS Level Converter and CHU Modem page. ...
