... evlist -- output event list . The output event list is a clone of the input event list in which the tables EVENTS , STDGTI0n , EXPOSU0n and REJPIXnn have been destructively filtered and the node-specific exposure maps have been deleted or replaced. The STDGTI0n tables and the REJFLAGS attribute of the EVENTS table indicate what filtering has been performed. ... The two exposure maps for a chip are not constructed unless the EXPOSU0n table for that chip is present in the input event list. ...

... The value of tile-size, NW , may be thought of as a sixth coordinate axis in the chirplet transform parameter space - TF-area. Including this sixth coordinate axis provides us with a hierarchical (multi-resolution) CCT. ... Various 2- D slices through the multiresolution CCT may correspond to useful tilings of the TF plane with true parallelograms (true to the extent that the DPSS define a truly rectangular region in the TF plane). ...

... We describe a new library (AST) which provides a flexible high-level programming interface for handling world coordinate systems in astronomy and for producing graphical output. ... Relationships between coordinate systems are represented within AST by objects called Mappings. ... While Mappings represent the relationships between coordinate systems, the coordinate systems themselves are represented by objects called Frames. ... Like all objects, a Frame also provides methods. ...

... The first two catalogues (the one has been calculated using all input catalogues and the second one using only catalogues obtained with CALC/SOLVE software) provide a stochastic improvement of the ICRF 2. and the last two of them one allow us to account also for systematic errors in the current ICRF version. ...
