Ifocas is esentiallyy the same FOCAS package
but now is tied to the IRAF system
hence it supports IRAF images format; in particular, FITS format.
The tasks available
in IFOCAS are:
artcat
- create an artificial catalog
autofocas - automatic FOCAS processing script
autopsf - automatic
PSF estimation
catgraph - graph pairs of catalog fields
catlist
- list catalog fields
catparams - create or modify catalog non-interactively
catsort - sort
catalog by certain fields
clean
- replace objects by sky
detect
- detect objects in an image
evaluate - evaluate photometry
and astrometry of objects in a catalog
expsf
- extract the PSF description from a catalog
filter
- filter a catalog
findstars - algorithm to automatically
find stars
info
- list catalog header information
mask
- create a mask image from a catalog
merge -
merge catalogs
newres - new resolution
classifier
nobjects - list the number of objects
in categories from a catalog
objimages - extract object images to individual subimages
resolution - resolution classifier
review - review catalogs
select
- select objects by identifier from a catalog
setcat
- create or modify catalog interactively
setpsf
- set the PSF description in a catalog from a text file
skip
- select fields in a text stream skipping some fields
sky
- evaluate the sky for objects in a catalog
splits
- split merged catalog objects in an image
template - create a PSF template from
a catalog of objects
totmag - evaluate the
"total" magnitudes for split objects
unsplit - remove
split objects and reset object flags in a catalog
# MATCH CATALOGS AND OPERATE ON MATCHED CATALOGS
catmatch - match objects in single catalog
to form a matched catalog
mcatlist - list cataog fields
from a matched catalog
mchmag - change magnitude zero points
in matched catalog
mextract - extract a single catalog from a
matched catalog
mfilter - filter
a matched catalog
minfo -
list matched catalog header information
mreview - review a matched catalog
mstat -
compute matching statistics from a matched catalog
# GENERAL STREAM TOOLS
binstrm - bin values in an input
text stream
fltstrm - filter values
in an input text stream
opstrm - operate on an input
text stream
statstrm - compute statistics from an input
text stream
