Description: # Discrete Sky Operator (DiSkO) Synthesis Imaging

        Its so cool its POINTLESS. Image by using the telescope operator keeping track of the telescope null-space and range-space. This software 
        carries out a sparsity reduction by regularization and controls the volume of the sky solution. The result is an imaging algorithm that is sensitive to diffuse broad sources, and does not require restoration like CLEAN. Publications to appear :)
        
        ## Howto
        
            disko --display --show-sources
        
        To load a data from a measurement set 
        
            disko --ms test_data/test.ms --tikhonov --nside 32 --PDF
        
        ## VLA imaging with DiSkO
        
        Download the VLA 5GHZ continuum survey measurement set. AG733_A061209.xp1 from the NRAO site.
        
        Calibrate and then split the measurement set, following the CASA tutorial [https://casaguides.nrao.edu/index.php/VLA_5_GHz_continuum_survey_of_Seyfert_galaxies]
        
            disko --fov 0.01 --ms NGC1194.split.ms --SVG --arcmin 0.0025 --tikhonov
        ## More challenging
        
        This tutorial should generate a file with lots of diffuse radiation. 
        [https://casaguides.nrao.edu/index.php/VLA_Continuum_Tutorial_3C391-CASA5.5.0]
        
            wget http://casa.nrao.edu/Data/EVLA/3C391/3c391_ctm_mosaic_10s_spw0.ms.tgz
            wget https://github.com/jaredcrossley/CASA-Guides-Script-Extractor/blob/master/extractCASAscript.py
            
            python extractCASAscript.py 'https://casaguides.nrao.edu/index.php?title=VLA_Continuum_Tutorial_3C391-CASA5.5.0'
        
        Then in CASA
        
            execfile("VLAContinuumTutorial3C391-CASA5.5.0.py")
            
        This should generate a suitable measurement set to image.
