... Science . ... The goal is to bring together two communitities: the one working on star formation (mostly galactic) and the one working on the formation of young massive clusters (mostly extra-galactic). We will link galactic with extra-galactic work, optical/NIR techniques with sub-mm/mm/radio ones, the formation of stars with the one of massive star clusters - observations and theory. ...

. Next: Routines of the Calibration Up: Coordinate Definitions used by Previous: Spatial coordinate systems Contents . Several calibration entities are time dependent, i.e., change on a time-scale given by the typical duration of an observation ( ksecs). Each corresponding CAL subroutine receives a time argument which specifies a point in time represented as ellapsed number of seconds since the fixed mission reference time . 1998-01-01T00:00:00.00 TT = 1997-12-31T23:58.56.816 UTC .
