... This task operates on event data in an event list. ... In the first two cases, the celestial coordinates of the reference point are taken respectively as the values of the RA_NOM , DEC_NOM or RA_OBJ , DEC_OBJ values in the input event file header. ... Although the OM attitude information may be more accurate, it will not be present throughout part of the observation, and as such, the default source for the attitude data should be "ahf". ...

Next: ASCII source files Up: Getting started Previous: Getting started . The essential data needed for program stars are names, positions, and the equinox to which the positions are referred. ... The command MAKE/STARTABLE helps you create a table of program stars. Some telescopes record the position toward which the control system thinks the telescope is pointing as part of the data stream, so it is tempting to extract these data to make a positional catalog for the program stars. ...

... In the framework of a collaboration between ESO and OAT concerning the development of a data reduction pipeline and the related quality control subsystems software for UVES/VLT, a detailed feasibility study is being performed on the basis of data extracted from the EMMI/NTT archive. ... It is ESO policy to perform data reduction for VLT instruments in ``pipeline" mode, either at the observing premises or at headquarters. ... archive data were processed in pipeline mode; . ...
