Computer Ephemeris. Ephemeris for physical observations of the planets. Explanations. Each row of the table contains for date specified at 0h of Time Terrestrial Dynamical: . ... position angle of axis of planetary rotation (degrees) - 'P', . ... illumanated part of the disk - k, . ... position angle of disk point with minimal illumination (degrees), . longitude of central meridian of the disk (degrees) - 'merid1' - system I and so... phase correction (degrees). ...

... Next: The PROS Big Up: Software Systems Previous: Data Reduction Software . ... The srcinten task provides PROS users with a tool to compute count rates for point sources in the ROSAT High Resolution Imager (HRI). ... Corrected upper limits are cited at locations where the count rate falls below the source detection threshold. ... Srcinten is a new PROS task that computes and applies the above correction factors to the net counts in a user-specified aperture. ...

... Categories: calibration GPDOF estimates the likely error in a calibration solution, by calculating the errors in the "Degrees-of-Freedom" (dofs) of an interferometer. This is useful for calibration of high-precision circular polarization observations. ... Finally, GPDoF calculates the std and standard error of the derived dofs, which you can use to estimate the errors in the Stokes V of a target observation. ... GPDoF estimates the std and standard error in the dofs. ...

RATAN-600 radio telescope . ... In the "radio-Shmidt telescope" mode the antenna system the South sector of the main mirror with the flat mirror ("South+Flat") of the RATAN-600 radio telescope is used. ... The antenna system the South sector with the flat mirror. ... The flat and circular mirrors of the RATAN-600 form the basis of the system. ... In the case of antenna system "South+Flat" the planoid is flat mirror, the circular reflector of RATAN-600 is the second mirror. ...
