Context. Thermal emission by stochastically heated dust grains (SHGs) plays an important role in the radiative transfer (RT) problem for a dusty medium. ... Aims: We define an appropriate problem for benchmarking dust emissivity calculations in the context of RT simulations, specifically including the emission from SHGs. ... It also includes a series of analytically defined radiation fields to which the dust population is to be exposed and instructions for the desired output. ...

... We have calculated the binary coalescence rate with time using the ``Scenario Machine'' code, which allows us to simulate evolution of large ensembles of binary stars in an artificial galaxy using a Monte Carlo method (see Lipunov 1992, Lipunov et al 1994, 1995 and references therein). ... The source evolution in a galaxy with given star formation rate is thus calculated as , where is the redshift at the turn-on of star formation, which is the second important parameter of the model. ...

... 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. ...

... The file names' construction . The flight (m) stage's file set . ... the orbital data used for the flight operation monthly (m) long-term planning, . ... The orbital calculations are based on the initial orbital data determined by KIAM RAN using the orbital radio- measurement treatment. The determined initial orbital data are presented as a state vector (satellite position and velocity) in the J2000 reference. ... Accept the file with extension '.bgr', where the Moscow time (MT=UT+3h) is used. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... The RA_PNT , DEC_PNT and PA_PNT keywords, together with the AVRG_PNT keyword which records the type of average used, are meant to describe the average value of the spacecraft attitude during the exposure. ... attsource =`binned': whatever values of the PNT keywords calculated by attbin and stored in the inbinnedattset dataset are simply copied over. attsource =`odf': PNT values are sought from the header of the dataset pointed to by pntkwdset . ... In this case AVRG_PNT is set to `FIXED'. ...
