Table Format :

Tables are ensembles of columns strictly equivalent to the formatted files. The only difference is that they are unformatted, and hence access time is typically 50 times faster... The number of lines is fixed, but the number of columns may be extended indefinitely. In fact, a table may be consider as a 2-D image (and vice-versa if you want) but does not require ``axis'' information... Tables can be accessed in command COLUMN using option /TABLE instead of /FILE. Using tables is recommended whenever a large number of rows or columns. Two programs can be used to convert from tables to formatted files (GILDAS_RUN:LIST.EXE) and vice versa (GILDAS_RUN:TABLE.EXE).
