The preliminary version of documentation of the format for the interchange of calibrated optical/IR data being developed by Tom Pauls of NRL and John Young of COAST was presented and a number of issues discussed. The proposed format is in the general form of a relational database with different components stored in FITS binary tables. ... Should there be a single data table type that includes all data types, or multiple table types, one per data type? What data types are needed? ...

Next: Biases Up: Contents Previous: Stars without Periods . Based on the data presented in Figure , I can suggest several conclusions about the evolution of young stars. The results of the Kolmogorov--Smirnov (KS) tests with the data presented here and those of Choi & Herbst (1996) on similar regions of the histogram indicate that there is something which holds stars near eight day periods. Stars in different regions also seem to share a similar mechanism which regulates the fast rotators. ...
