Software Release

CASUTOOLS

CASUTools is a package of several programs that we routinely use on the pipeline processing we carry out at CASU. At the moment it contains the following tools:

  • The image object detection and parameterization (imcore, imcore_list and classify)
  • The image stacking and dribbling software (imstack, dribble)
  • The astrometric fitting software (wcsfit)
  • Background filtering to remove large scale structures (nebuliser)
  • The software to do the final mosaic of a list of image extensions (mosaic, grout, ungrout)


DOCUMENTATION

The usage of each application is documented in imcore, stacking, wcsfit, nebuliser, mosaic, dribbling, grouting, ungrouting, VST pickup and classify.

 

Installation

The software has been tested in different Linux distributions, 32 and 64bit, Solaris and OSX. It requires a C compiler to build and recent versions of the CFITSIO and WCSLIB libraries installed in your system. See the README file in the distribution file for instructions on how to build the software. For most of the systems you just need to do

./configure && make && make install

In those cases where the FITSIO and WCSLIB libraries are not in a standard location you will need to specify additional flags to configure as in e.g.

./configure --with-cfitsio=/sw --with-wcs=/sw

DOWNLOAD

Last version is 1.0.25 can be downloaded from here. We just ask for your name and email so that we can inform you about updates or new versions.

FITS to ASCII catalogues

The fitsio_cat_list program can be used to convert the FITS catalogue tables into ascii applying all necessary corrections. It is a fortran program available to download separately below. It needs the CFITSIO library and can be compiled as
gfortran fitsio_cat_list.f -o fitsio_cat_list -L/sw/lib -lcfitsio -lm
and then run as
fitsio_cat_list catalogue.fits

It writes a file named catalogue.asc with the following columns: RA and Dec coordinates, x, y, magnitude, magnitude error, chip number, stellar classification, ellipticity and position angle. Additional columns can be added by editing the source code which is available for download at the bottom of this page. 

Note that v1.7 onwards now uses double precision arithmetic for the relevant part of the astrometric conversion since the original single precision version limited the external accuracy to up to ~50-100mas, particularly for fields with large RA.

The latest version is v1.8 (20120812).
