... It provides long range planning information to the scheduling team; it provides bright object, timing, and orientation information to the observation planning team; and it provides graphical description of the observations and their constraints. ... The GUI graphically displays the constraints that are computed by Spike and stored in the description files and in the database. ... BOAS processes all bright objects that have entered the database since the last time BOAS was run. ...

Jeff mock supplied 6 different types of filters to use with the high resolution mode of the mock spectrometer. ... Plots were made of the time domain voltage response as well as the frequency domain power response. A decimation of 10 was used for the filter decimation. this gave a filter length of 80 coeff. The plots compare the filter shapes for these filter types (.ps) ( .pdf ) . ... Each color is a different filter type . middle: spectral density reponse for each filter . ...

. 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

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. ...

... ALMA . ... OOF software . ... Software . ... We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. Notable features are simulating three dimensional turbulent volumes instead of flat phase screens, considering three representative configurations of ALMA and parametrisation in terms of phase fluctuations on a 300m baseline, allowing referencing to the site-testing interferometer data. ...
