... Three different techniques for averaging have been introduced. ... The average functions mentioned above will normally produce a result frame whose world coordinates are the intersection of the father frames' world coordinates. ... Averaging statistically consistent values --- љ This command differs somewhat from the purely mathematical functions of the previous two commands in the sense that it tries to anticipate some of the astronomical content of the input data frames. ...

... CentralProcessor 0.11 documentation . ... The parameters listed here allow the user to configure the parset and the slurm job for continuum imaging of the science field. Some of the parameters can be set to blank, to allow cimager to choose appropriate values based on its ?advise? capability (which involves examining the dataset and setting appropriate values for some parameters. ... Number of CPUs to use on each core in the continuum imaging. ... User Parameters - Continuum Self-calibration . ...

... overview of pyQC . ... output used by . ... All pyQC scripts and modules share a similar structure. Python offers to group functions, classes, etc. into modules which can be imported by different scripts. ... In order to avoid confusion if names are used by different (especially external) modules, the QC scripts use the 'from' statement only for pyQC modules, i.e.: . ... For other modules, the simple 'import' statement is used: . ... Python modules are also used for keeping script configuration. ...

... An error involving a missing tasks parameter indicates that the parameter file may have changed between the last time the task was used and the current version. ... If still in trouble, delete the parameter file in `myiraf/uparm' corresponding to the task (the names are somewhat contrived, but with a bit of imagination it is not too difficult to identify the right one). ... The imcnts task and region masks . ... A region descriptor of the kind: . CIRCLE(403, 403, 22.5) . ... See `help regions'.) ...

... This page will contain a form to pass parameter values for a on-line working code producing figures illustrating the dependence of optical properties of different scatterers on their parameters. Specify the parameters and press start calculation button to produce a figure. ... Independent variable: x v a/b alpha Re(m)? another? ... Number of curves: 1 2 3 . ... Curve #1: .

The determination of the detector parameters is based on sets of images of a spatially uniform-illumination scene (flatfield frames) and without any illumination (dark frames), putting a plug in place of the filter, taken at a series of exposure times. ... We interleave before and after each exposure time in the series of flatfield frames a set of reference images at an exposure time of 1 sec to determine the possible temporal variation of the illumination level. ...

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. ...

... The described algorithm is suitable for measurements of complex images of stars. ... a) the zero-based number of stars in the complex (multicentric) image, . b) set of preliminary coordinates - x i , y i , for all stars, index i is number of a star, . ... i - index of a star in the complex image; . ... These parameters are calculated by a nonlinear method of a least squares.The main output parameters of this algorithm are x i , y i ; where the index i is number of a star in the multicentric image. ...
