Section I: Introduction to ALFA and GALFA . Section II: System Description . ... ALFA receives 7 beams, 2 polarizations per beam, each covering 1225-1525 MHz. The 14 IF signals cover nominally the 100 to 400 MHz band. ... A high-resolution, low-bandwidth spectrometer (8K channels covering a 7 MHz bandwidth) . ... Each spectrometer board handles two polarizations from one telescope beam.The baseband signals are to be digitized by four 8-bit ADCs at 100 Msamples/sec. ... Bandwidth: . ...

Next: Observations and Analysis Up: The Second EGRET Catalog Previous: The Second EGRET Catalog . ... The first EGRET catalog ([ Fichtel et al. 1994b ]) covered Phase 1 of the Compton Gamma Ray Observatory (CGRO) viewing program which began shortly after launch of the observatory on 1991 April 5 and ended on 1992 November 17. ... No additional solar flares were seen during Phase 2; therefore, the first EGRET catalog summary has not been updated in the present work. ...

... Perform basic two-dimensional image reduction. Reject cosmic rays from CCD data. Process the contemporaneously obtained wavecal data to obtain the zeropoint shifts in the spectral and spatial directions. ... Subtract science image from wavecal . ... For each image in the science file, this task selects the wavecal in the wavecal file that is closest in time to the science image, and it copies the keyword values for the spectral shift from that wavecal header to the science header. calstis12 . ...

... The Raw Images . Table 1: List of Viking Orbiter Images of the "Face on Mars" . ... Processing the Face Images . ... In July, 1976, Viking Orbiter 1 was acquiring images of the Cydonia region of Mars as part of the search for potential landing sites for Viking Lander 2. ... Using the height field, it is also possible to view the "Face" from different look directions, by mapping the Viking Orbiter image directly on the the topography and then placing the "viewer" at different locations. ...

This page will provide interested persons with both the raw Viking images, transformed to GIF format, and a brief tutorial (with examples) of image processing techniques applied to create "better looking" images. ...

Next: Three-dimensional Data Analysis in IRAF and ZODIAC+ . ... A data analysis system has been developed at SRON, which has been designed to allow rigorous control of the quality of its processed data products. ... This means recording all parameters of all steps which lead to the establishment of the final data products (Figure 1 ). ... Figure: A processing pipeline is a sequence of tasks with several input/output files and parameters, which pass data from one task to the next. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

Data Processing . S2 or VLBA tapes containing the astronomical data recorded at tracking stations and ground radio telescopes must be sent to correlation center chosen by the principal investigator (PI). ... There are four correlators, which will be able to process RadioAstron data: DRAO S2-correlators in Canada, NRAO VLBA-correlator in USA, and Mitaka correlator in Japan. ... Data and Phase Links . Ground Support of the RadioAstron . ... Progress of the RadioAstron Project in Pictures . ...

... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

Next: Using SPC Up: SPC (formerly S) A Previous: Contents Contents . SPC was originally written to process data written by SPECTRA , the spectral-line observing program of the Parkes radiotelescope. While SPC 's data structure and many of its commands are Parkes-specific it has been adapted for use by a variety of other telescopes (e.g. the AT, Nobeyama). ... The basic idea in using SPC is to load in a sequence of up to 110 spectra and then use various commands to operate on these spectra. ...
