Next: Creation of the Up: The Data Organizer Previous: Checking the quality . The association of scientific frames with suitable calibration images is achieved by selecting and ranking all calibration frames which for a given scientific exposure match a set of user defined selection criteria. ... For instance, this may in natural language be expressed as: ``Find for each scientific frame 2 dark exposures which have been observed within the same night. ... Association of Calibration Exposures . ...

... HST . WF/PC-1 Data Handbook . ... Retrieving HST Data . ... When dealing with the spherical aberration, point spread function (PSF) images are often an important element in the deconvolution of WF/PC-1 data. ... A complete PSF image name consists of the PSF rootname as provided in DATA_FILE column of the tables in the WWW memo plus the suffixes . ... Except for very short exposures, both the observed and modeled PSFs will not perfectly match WF/PC-1 images due to the jitter in the HST pointing. ...

... A star was observed at different zenith distances during one night at the Engelgardt's Astronomical Observatory in the program of atmospheric extinction study at blue. ... The determination of the star's brightness was performed with the method of photon counting. ... Variable star. ... The brightness of the variable star was measured occasionally during the other nights, and moments of maximal values of brightness (15.59m) were received on nights 2­5, the 2nd table. ... JD 2452805. ...

LARGE-SCALE PHENOMENA AT THE SUN ASSOCIATED . WITH FILAMENT ERUPTIONS OUTSIDE ACTIVE . ... Considering the 12.09.1999 event as an example, we analyze manifestations of large-scale disturbances associated with coronal mass ejections (CMEs) caused by filament eruptions outside of active regions. ... The filament eruption occurred in relatively weak magnetic fields, but it was accompanied by larger-scale phenomena than flare events do. ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... 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. ...

... 2001 September 1 . Magnetars In The Sky . Picture Credit: E. L. Wright ( UCLA ), COBE Project, Courtesy MSFC , NASA . ... How strong is a magnetar's magnetic field? The Earth's magnetic field which deflects compass needles is measured to be about 1 Gauss , while the strongest fields sustainable in earthbound laboratories are about 100,000 Gauss. A magnetar's monster magnetic field is estimated to be as high as 1,000,000,000,000,000 Gauss. ... About APOD | ... NASA Technical Rep.: ...
