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. ...

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 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. ...

... In most cases it will however be necessary to compute an appropriate airmass using the COMPUTE/AIRMASS . ... It is important to keep in mind that ``mean airmass'' and ``mean atmospheric extinction correction'' are different from the values at mid-exposure, especially for larger zenith distances. ... For reasonable combinations of exposure time and zenith distance, the weighted mean airmass supplied by COMPUTE/AIRMASS should be appropriate. ...

Computers become more and more popular nowadays. That means that the amount of people who are able to work with computer programmes and play computer games has increased. In many cases computer games are the only thing that a person is accustomed to. ... As a result of this epidemic "homo playing" may put on the isoreality helmet which makes a person, crazy about games, forget about food, slumber and all other components of real life: "homo playing" becomes isolated from community. ...

... A well known problem with EOP prediction is that a prediction strategy proved to be the best for some testing period and prediction length may not remain as such for other period of time. In this paper we consider possible strategies to combine EOP predictions made using different analysis techniques to obtain a final prediction with the best accuracy corresponding to the least prediction error between input predictions. ... C2 ­ best previous prediction for given length. ...
