... CHECK/ROMAFOT cat_tab reg_tab err_mag . ... This is accomplished by comparing the instrumental magnitudes and positions (recorded in the catalogue file generated by ADDSTAR/ROMAFOT ) with that derived through the complete procedure and recorded in the output table. ... In addition, CHECK/ROMAFOT modifies in the catalogue table the positions setting flag to 1 for the objects that have been recovered, while this flag remains set to 0 for the undetected ones. ...

. Next: Generation from In-Orbit Data Up: EPN_ADUCONV Previous: Description Contents . Ground calibration data obtained from extensive measurements of X-ray emission lines and synchrotron lines (mainly flat fields). The gains of the individual readout nodes are derived by comparing the positions of the CTE corrected calibration lines (in ADU) with their energies. Michael Smith 2011-09-20

Dust in galaxies can be mapped either by the FIR/submillimeter emission, the optical or infrared reddening of starlight, or the extinction of a known background source. ... We find that distant galaxies are predominantly in low-extinction sections marked by the color maps, indicating that their number depends both on the cloud cover of Spitzer-resolved dust structures, mostly the spiral arms, and a diffuse, unresolved underlying disk. ...

... the computed pointing error for different vertical offsets (.ps) ( .pdf ): . the measured platform height offset and pointing error (.ps) (.pdf ): . ... This gave us a dataset of a pointing run with simultaneous info on the vertical error in the platform position The plots show the measured platform height offset and pointing error (.ps) (.pdf ): . ... The pointed error computed from the height offset matches the measured za error offsets when the platform is offset in height. ...

... The ob ject catalogue and compressed pixel data are stored online and are accessible via the WWW. ... Available Services The SSS data consist of ob ject catalogues to the plate limits from BRI plates including astrometric and photometric calibration. ... The primary data format is FITS for both images and binary tables of ob ject catalogues, which enables porting of the data into established software packages. Ob ject catalogues are additionally available in plain text format for readability. ...

Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...

... Virginia Kilborn's program gfinder was run on 388 luthered and edge-masked HIPASS cubes , covering the whole southern sky, over all 1024 channels (i.e. -1281 to 12741 km/s), with an HI peak flux cutoff of 60 mJy/beam. ... The large number of candidates is mostly due to artifacts generated in areas of strong continuum flux, mostly the Galactic Plane, (causing a baseline ripple), the HI emission in our Galaxy, and lots of interference (1408 MHz birdie, GPS etc.) ...
