... Magnetic fields, subatomic particles, etc., traveling in different directions fill the universe. Do they deflect or otherwise affect one another? If so, isnт??t the information we get from them distorted? ... Neutrino astronomy, which is still in its infancy, is attractive because neutrinos interact so weakly with matter that few of these distorting effects occur.

... Figure 1a illustrates the summary diagram (2 log L, log S ) based on the field intensity contour lines for 7 active regions plotted at 200 G steps in the range of 2200­400 G. One can see that the relationship under discussion is well represented by two straight lines, one corresponding to the log S range from 2 to 7.2 and another, from 7.2 to 9. ... Then, we plotted 2 log L versus log S for all field lines of a given intensity, no matter which sunspot or sunspot group they belonged to. ...

... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....

... 1997: . As a result of comprehensive RATAN-600 studies of the prominence on the W limb of the Sun, its instant detailed radiation spectrum in the range from 1.7 to 32 cm (at 39 different wavelengths) was obtained for the first time. ... Own radio emission from the lunar crater Copernicus was registered for the first time at 1.38 and 2.7 cm wavelengths in the RATAN-600 observations of the Moon. This indicates a temperature increase in this crater up to 100K at the depth of 5m. Archive . ...

... Previous: Residual Bias Removal in HST NICMOS Images . ... Bias frames taken with CCDs should be homogeneous in intensity. ... Using a large number of bias frames obtained in one specific run, the time-dependent pattern was found to be built up of a fixed one-dimensional periodic function whose phase-shift varies from row to row. It was successfully removed from calibration and science frames through the use of pre- and upscan ``bias'' pixels available in each of these frames. ...
