PURIFY
----------------------------------------------------------------
DESCRIPTION
PURIFY is a collection of routines written in C that implements different
tools for radio-interferometric imaging including file handling
(for both visibilities and fits files), implementation of the measurement
operator and set-up of the different optimization problems used for image
deconvolution. The code calls the generic Sparse OPTimization (SOPT)
package to solve the imaging optimization problems.

EXPERIMENTS
To run an example with a simulated AMI coverage and a 128X128 M31 test image,
run the script example_ami.c.
To run an example with a simulated variable density coverage and a 256X256
version of M31 as test image, run the script example_m31.c.
To run an example with a simulated variable density coverage and a 256X256
version of M31 as test image, run the script example_30dor.c.

INSTALLATION
To install the toolbox, the CFITSIO library
(heasarc.gsfc.nasa.gov/fitsio/) and the SOPT toolbox
(github.com/basp-group/sopt) must be installed.
A makefile is provided to build the code. Before compiling you
might need to edit the makefile to specify your compiler and the
location where the dependencies are installed. Once these are
installed you just need to type
%make all
to install the toolbox.
