The pdev spectrometer dshift parameter (see layout of spectrometer scaling ) down shifts the output of the power computation before accumulating the spectral values in the 40 bit accumulators. ... As an example: a 1 second integrations at 170 MHz with: (A/D=48,pshift=0x1555, dshift=0,ashift=0) has LO feedthrough birdies close to 1.5e9. The maximum allowed value is 4e9. ... The allowable range for dshift had been computed from the spectral mean with dshift = 0 (see page 2 of the plots) . ...

Computer Ephemeris. Second order reduction quantities. Explanations. This page consist of four little tables. First and second tables contains J a (in 0.000001 s ) and J d (0.0001") for nothern declination, third and fourth contains the same information but for southern declination. Each table have 13 informational columns headed with right ascension values, and some amount of rows, labelled with date. ...

Next: The ST-6 Up: CCD Systems and Previous: The Lynxx . The SBIG ST-4 uses the same CCD chip that is used by the Lynxx. The ST-4 uses a CPU box as opposed to a card that must be installed in the computer. This makes the ST-4 more portable than the Lynxx, since it can be run by a laptop computer for imaging, or with just the CPU box for guiding. ... The ST-4 is also capable of moving the telescope. ... Its purpose is to allow the CCD computer to communicate with the telescope's drive. ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... We then updated to PVCam 2.7.4.2, but we still see corrupt images if we don't close and reopen the camera after every exposure sequence, and the camera sometimes fails to respond to a trigger pulse. ... Close and re-init the camera, as follows: ... pl_cam_close(0) pl_pvcam_uninit() pl_pvcam_init() . ... power off camera . ... Call pl_exp_start_cont (to start a continuous exposure sequence into a circular buffer) with a circular buffer that holds too many images and you will hang your computer. ...

A very important stage in a story of formation of any new science is the shift from discussion of situation which are possible but do not occur in practice due to some reason to recognition of real phenomena of interest. ... We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ...

... When the computer loads a boot sector on a normal Linux system, what it loads is actually a part of lilo, called the ``first stage boot loader''. ... This reads the configuration file /etc/lilo.conf and writes the boot loaders, and information about the operating systems it can load, to the hard disk. ...
