Next: Other deconvolution tasks Up: Image Deconvolution Previous: Computation . If you have used multi-frequency synthesis in the imaging stage, you will have to have considered a fly in the ointment - the flux density of the source will vary with frequency (as well as spatially). For detection and low dynamic-range work, mild spectral variation can generally be ignored. ... The Miriad deconvolution task mfclean can be used to avoid this distortion. ...

... Previous: ESO C Library for an Image Processing Software Environment (eclipse) . ... A new CLEAN-type algorithm searches for model components not in the dirty image but in the multi-resolution wavelet transform of the dirty image based on the dirty beam. ... The improvement of this prototype Wavelet CLEAN, which does convolve with the dirty beam, can be attributed to a suppression of noise and aliasing in the dirty image by use of information in the sidelobes of the whole image domain. ...

Alexander S. Dmitriev . Institute of Radioengineering and Electronics of the Russian Academy of Sciences . Mokhovaya st., 11, Moscow, 103907, Russia. ... Moscow Institute for Physics and Technology . ... The relationship between the problem of cleaning chaotic signals off noise and the information properties of the signals is shown. Some methods for chaotic signal cleaning are considered. The efficiency of these methods is evaluated by computer simulation. ...

This button takes the displayed number of CLEAN components and adds them to the current model. It also subtracts these components from the data, runs self-cal and displays the updated residual and final maps. CLEAN components added to the data cannot be removed unless the model is cleared completely and CLEAN restarted (use "Clear" button).

In 2005 we have made some attempts at cleaning up the rfi in the 327 Mhz receiver band. ... sept05)It produces combs at: . ...

The 327 Az swings showed that the 327 Mhz birdies have an azimuth dependence (which means they are coming from outside the dome). home_~phil ...

... 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. ...

... This section describes three functions which have been created to cleanup defects in images. The first two functions for cleaning rows and columns are particularly useful for CCD--images. ... These can often be removed with the commands: MODIFY/COLUMN INPUT OUTPUT [C or V] [columns] . ... This is particularly useful for removing the permanent defects which may exist in the CCD--frames and which cannot be removed by the MODIFY/COLUMN or MODIFY/ROW commands. ...

. I restored the ability to subset the image being drizzled even though the code does not currently use it. I cleaned up stuff for subversion, getting ready for the big merge. I checked the code against the Drizzle Handbook and it matches the formulas in there. But I still have some qualms about how the code works and will do a few more tests. Search . Pages . Front Page .

On 12/1/97 I got the first clear night since 1997dt was reported. I just took the camera apart for cleaning, and I didn't get a chance to make twilight flat fields tonight. Thus the edge is darker than the center of the field. I'll correct this if it's clear tomorrow night. The image was taken with C14 @f4 and CB245 CCD camera. ... The field of view is about 12 X 9 arcmin. The supernova is the star just west (right) of the nucleus. Back to Supernovae in NGC and IC galaxies. ...
