... The Miriad task uvgen can be used to simulate a variety of observing modes. ... Simulating a telescope approximately, let alone in some detail, requires a good many parameters. uvgen takes an appreciable number of parameters and input files to describe the telescope, correlator and source. Fortunately keyword and set-up files for some common situations exist ( e.g. simulating the ATCA and VLA). ... For example, to load typical parameters for the ATCA, use miriad% source $MIRCAT/uvgen.def.atca . ...

Arecibo Upgrade Notes INSTRUMENTAL POLARIZATION : POLARIZATION ISOLATION ERRORS IN STOKES PARAMETERS Jim Cordes Joe Lazio 22 May 1996 Summary The purpose of this memo is to: 1 demonstrate how polarization isolation is related to errors in Stokes parameters ; 2 estimate a tolerable level of errors in Stokes parameters due to amplitude and ... There we had a level of cross coupling that gave about 10 errors in Stokes parameters. ...

... Calculations of at least two runs with different values of a parameter are required in order to discover to what extent the results depend on the , if at all. ... In order to study how the final statistical distributions depend on the initial functions, the method of Green functions is used. ... Then we can restore any distribution on this parameter (with a certain accuracy) by summing the results for each interval with the appropriate weight. ...

... When creating a mosaic from a set of individual frames, the correct background offset for each frame must be determined for proper matching. In this paper we describe a method for constructing a mosaic from a set of individual frames by applying a minimization technique. ... Typically these are frames with some known defect (see ? ... Determining which frames to exclude from the final mosaic is critical, since one bad frame can create background offset errors that propagate throughout the mosaic. ...
