... The degradation correction coefficients have been calculated by a linear fitting to the measured counts (coincidence loss corrected) of the stars BPM 16274, Hz 2 and GD 153 observed periodically since the beginning of the mission. The fit is done for each filter as a function of the MJD of observation, using the data of all stars. These stars are observed once per year (BPM 16274 twice) to monitor the variation of sensitivity.

... The Miriad task uvgen can be used to simulate a variety of observing modes. ... Simulating a telescope approximately, let alone in some detail, requires a good many parameters. uvgen takes an appreciable number of parameters and input files to describe the telescope, correlator and source.

For example, to load typical parameters for the ATCA, use miriad% source $MIRCAT/uvgen.def.atca . ...

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. ...

Using Ly alpha line profiles generated from a grid of M dwarf model atmospheres we calculate the attenuation factor [i.e. Ly alpha (obs)/ Ly alpha (intrin)] due to the interstellar medium as a function of hydrogen column density. ... The major uncertainty in this work has been the interstellar hydrogen column density, emphasizing the need for further work in this area and in particular an accurate model of its variation in all directions. ...

... In order to compare the number of different evolutionary stages obtained and X-ray luminosity of the chosen X-ray sources with the observed galactic values we use the sum of C/O+O/C , where C and O are the calculated and observed values of a given binary type, respectively. If we make comparison for a number of different binary species (for example, we compare the number of CV, number of X-ray pulsars,   total X-ray luminosity of LMXB, etc.), we write this criterion in the form: . ...
