Hi JJ,
I am about to move ldacs catalogs (only available catalogs for fields
without chi2 image, i.e. with a missing image among filters g, r, or i).
But I do not remember how you'd like them:
- as is, .ldac
- gzip compressed, ldac.gz (not so efficient ~80% compression ratio)
Which one do you prefer ?
Those files can easily be transformed into ASCII with new E. Bertin's tool
"ldactoasc" made for this purpose, available in the latest SExtractor
distribution (via svn):
http://terapix.iap.fr/wsvn/index/public/software/sextractor/
Syntax: ldactoasc toto.ldac > toto.cat
NB: those ldac catalogs do not have the same content as the catalogs
extracted from chi2 images, they have less columns.
Cheers,
Fred.
