... First of all, I should say that you cannot guarantee user-mode processes to have exact control of timing because of the multi-tasking nature of Linux. ... However, for most applications using I/O ports, this does not really matter. To minimise this, you may want to nice your process to a high-priority value (see the nice(2) manual page) or use real-time scheduling (see below). ... Linux 2.x kernels have soft real time support; see the manual page for sched_setscheduler(2) for details. ...

... We have been upgrading the software front-end to WASP (Wideband Autocorrelating SPectrometer, operating from 800 to 4000 MHz) from Lynx-OS to Real-Time Linux and will discuss Real-Time software aspects. We are using a standard parallel ``PIO'' card to receive data from the spectrometer and standard GPIB interfaces that drive a frequency synthesizer for bandpass calibration. WASP and its front-end computer are fully mobile and can be taken to any suitable radio telescope. ...

. Computer Ephemeris. Sidereal time. Explanations. Each row contains at 0h of Universal time: month, day, real sidereal time (hours, minutes, seconds), mean sidereal time (only seconds, as a rule, hours and minutes are the same as in real time) and nutation in right ascension: long periodic (with periods greater than 35 days), and then short periodic (periods less than 35 days). Standard IAU 1980 nutation theory is used.

. As you probably have seen, the star in my original image is not nova. When I looked images from others, I noticed, that the star which i marked for nova in my image, is really a very faint doublestar. After more processing for my original image and compared it with Lick Observatory discovery image the real nova is now excatly in the right place. (Sept 4th, 1998) Marko Moilanen .
