... User Guide ] Task: clean Purpose: Apply Hogbom, Clark or Steer CLEAN algorithm to a map Categories: deconvolution CLEAN is a MIRIAD task that performs a hybrid Hogbom/Clark/Steer Clean algorithm, which takes a dirty map and beam, and produces an output map which consists of the Clean components. This output can be input to SELFCAL to self-calibrate visibilities, or input to RESTOR to produce a "clean" image. ... Key: map The input dirty map, which should have units of Jy/beam. No default. ...

Hi Tapasi, Please find attached the plots below for a few of the days that I retrieved using my own independent code. ... Another peculiarity I noted was that the break and shift in lambdas are not same for all beams (assuming there was one common error we would expect lambdas to shift the same way for all beams) so it seems Desh's code is calculating erroneous positions that depend on the beam number in some way. I am attaching only the beam 0 plots. ...

... For the Corner Method, Clean_lc was originally a FORTRAN 77 program developed by Steve Snowden and Kip Kuntz in 2005-6. ... Clean_lc's purpose is to clean a light curve by creating a histogram of rate values from the light curve, finding the most likely value assuming that to be similar to the mean of the quiescent rate, then fitting a Gaussian to a small window around that value in the histogram to determine the true mean and dispersion of the quiescent background rate. ...

Next: Image Processing of Digitized Spectral Data . ... We have proposed the 2-CLEAN DSA (Determination of Solution Area) method for the estimation of the area of possible images (from the ``obtuse" (smooth) to the ``sharp" variants) in complicated cases with constraints and poor information. ... The method of 2-CLEAN DSA allowed us to determine that the area of the permissible solutions lies formally between the ``sharp" (CLEAN) and ``smooth" (TC-CLEAN) variants. ...
