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. ...

... Abstract Determine the set of osculating conic orbital elements that corresponds to the state (position, velocity) of a body at some epoch. ... In general, the elements found by this routine can have two kinds of problems: - The elements are not accurate but still represent the input state accurately. ... One recommended "sanity check" on the outputs is to supply them to the CSPICE routine conics_c and compare the resulting state vector with the one supplied to this routine. ...
