... This paper describes distortion calibration procedures for the SOHO /LASCO-C2 Coronagraph, based on in-orbit data and extensive image processing methods. ... C2 suffers from moderate optical distortion, which must be corrected in order to properly locate the stars crossing its field-of-view (which are subsequently used for photometric calibrations), to retrieve critical attitude parameters, and to insure a correct overlapping of the region common to the C2 and C3 instruments. ...

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. ...

... We analyze relations between characteristics of an extended ensemble of Forbush decreases (FDs) caused by CMEs from the central zone of the solar disk during the 23rd solar cycle, on the one hand, and such solar eruption parameter as a summarized unsigned magnetic flux of CME-associated EUV dimmings and arcades, on the other hand. ... FD magnitude Figure 1a shows the relationship between the magnetic flux and the FD magnitude AF for events unambiguously identified with concrete solar eruption. ...

. Intervals of available data are coded by blue color. To read availability charts user should know the descriptor ("name") of the KP subset of interest. Table annotations include also number of version for each subset. Plot resolution is exactly one pixel per hour. Data are considered as available if at least one data point is present during that hour.
