... HST . ... HST Overview . ... Retrieving HST Data . ... The shape of the spectrum and its overall level are closely tied, which is why both sensitivity and vignetting were discussed in the previous section. ... Thermal drifts caused a spectrum to move on the photocathode, so the GHRS routinely performed a SPYBAL (spectrum Y-balance) to properly center the spectrum on the diode array. ... In some cases the shape of a spectrum can be distorted if the background is improperly calculated and subtracted. ...

IBIS Data Analysis . ... IBIS . ... Flat Fielding - Introduction . The images obtained by IBIS will have intensity variations across the field of view that are not due to the solar image, but rather caused by instrumental effects that alter the observed intensity in each point of the field of view. ... IBIS Flat Fielding Techniques . ... Therefore, it is desirable to obtain the flat field measurements center on a point along the equator near the heliographic center of the solar disk. ...

One of the rarest but most interesting effects which can be observed with the Irkutsk IS radar is anomal high power signal registraion(coherent echo) due to strong magnetic storms. ... These signals are formed at E-layer heights in the presence of a strong electric field which causes particles to drift. ...
