... The analysis of NICMOS polarization images is aimed at determining the Stokes' Parameters, and from those the polarization angle and degree for each pixel. NICMOS Camera 1 and Camera 2 each contain three polarizers, whose principal axes of transmission are separated by 120 degrees. ... The images in the three filters need to be compared, in order to produce the Stokes' parameters. ... The Stokes parameters can then be combined to yield the polarized intensity, I p: . ...

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. ...

... 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. ...

Phase Retrieval Measurements of Antenna Surfaces Using Astronomical Sources Bojan Nikolic, John Richer, Richard Hills Mullard Radio Astronomy Observatory, Cavendish Laboratory, Cambridge, U.K. Abstract We present a novel technique for accurate measurement of the largescale errors in an antenna surface using astronomical sources and detectors. Out-of-focus images of compact astronomical sources contain a wealth of information about the telescope optics. ...

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. ...

... First, we computed the mean errors of orbit parameters on the assumption of the linear connection of them with observation errors and then we compared obtained estimates with those resulting from the assumption of the nonlinearity of this connection. Secondly, we correlate orbital parameters and their errors obtained by the method of the least modulus with those obtained by the least-squares method. ...
