Mon 22 Aug 2016 11:42:21 AM UTC, original submission:

The utilities that require column numbers of tables (for example ImageCrop, or MakeCatalog), currently count from 0. This basically comes from the fact that counting in C starts from 0. However, when working with tables, counting usually begins from one (for example in AWK, or even CFITSIO).

It is thus much more convenient if the column counting of all utilities start counting from 1, not 0. There is probably no need to change the internal workings of utilities. The main work will be to change the value the moment it is read in: either from the command line (in `args.c') or if its is read by the configuration file(s) (in `ui.c').

Since we are still early in the development of Gnuastro, and probably not too many people are still heavily using Gnuastro, the sooner we do this, the better.
