History:
* 12-Nov-1999: first preparation
* 02-Mar-2000: In table4.dat, for GalNo = 112, the identification number
of Proust et al. was misprint, and changed in 75. 02-Mar-2000
* 03-Apr-2000: systematic errors in the [SDG99] number (column "Ref" of
table4.dat, when r_cz is 1) were detected and forwarded to Florence Durret.
Corrected [SDG99] numbers were supplied by Florence Durret.
