The OOF data reduction software is made available under the terms of the GPL V2 or (at licensee’s option) latter licences. For details of the licence see the files named “COPYING” in each of the distribution packages.
Please note that there is no warranty of any sort for this software. Consult the text of the GPL for details of the no warranty condition.
I am not funded to provide support for this software. If you wish direct question to me feel free to email, but understand if I do not have the time to reply.
Also, please note that this is primarily a research system that has grown during investigation and application of the OOF technique. As such, it is not designed to be an “end-user” system. Unless you can do C++ or Python programming it will be completely useless for you.
Phase retrieval holography with astronomical sources was initially investigated at the JCMT by R. E. Hills, A. N. Lasenby and collaborators in the early 1990’s. In 2000 I begun work with R. E. Hills and J. S. Richer on continuing these investigations.
The first generation of the OOF system that I wrote was designed to work within the software package that J. S. Richer wrote for reduction of with-phase holography for the JCMT. It was written in C++ and partially in TCL, and interacted with the user through the TCL interpreter.
The second generation system was re-written to be independent of the JCMT with-phase holography system. It also introduced interaction with user with Python rather than TCL.
The third generation system was a substantial re-write and redesign that improved the modularity of the system, reduced the number of dependencies and improved installation. This is the current generation. It is written in a combination of C++ and Python.
There is some additional information on using and building OOF software here http://wiki.gb.nrao.edu/bin/view/PTCS/OOFHolographyInstructions
Build system:
Required compilers:
Pre-required packages for the OOF holography software:
Following Python Libraries:
numarray
pyfits
V1.1 and numpy is installed then pyfits will use numpy by default. This is the pyfits+numpy configuration and it is not backward compatible with pyfits+numarray
The build system of the OOF software is the standard autotools chain, invoked by the ”./configure” command. Because the system is distributed as five separate components, it is necessary to configure each separately. This may be conveniently done using a script as below.
The following bash script illustrates the build procedure:
# Bojan Nikolic bojan@bnikolic.co.uk
#
# Bash script that illustrates building the OOF application
# Note: we are now using the pkg-config utility, simplifying
# installation considerably
export PKG_CONFIG_PATH=${OOFPREFIX}/lib/pkgconfig/
COMPS="bnlib-1.2.1 bnfits-1.2 astromap-1.2 bnmin1-1.3 oof-1.2"
for x in ${COMPS}
do
if [ -e ${x}.tar.bz2 ] ; then
tar xvjf ${x}.tar.bz2 &&
(cd ${x} &&
./configure --prefix=${OOFPREFIX} ${BOOSTFLAG} &&
make install
)
else
echo "Cant find ${x} !!!"
break
fi
done
If you wish to try reducing a typical OOF observation, I have posted a sample file. This is beam-differenced Q-band observation at the GBT taken in the spring of 2005.
Note
The versions of components comprising each release are a more definitive description of a build of the OOF system then the version shown in titles of these sections. So please cite versions of each component in any communication.
These are the components of the OOF software V1.3:
These are the components of the OOF software V1.2:
These are the components of the OOF software V1.1p1:
These are the components of the OOF software V1.1:
Versions prior to 1.1 are not being made available at this time.
