LAS\FILE IN Name Open an input file for reading. The input file can be of 2 different forms: - the usual Class Data Format (.30m or other produced by several tele- scopes, and by Class itself), - a VLM (Velocity-Position-Position) cube in the Gildas Data Format. LMV cubes must be transposed first to VLM before use. The usual Class commands (FIND, GET, etc) work transparently on both kind of files.
