... They normally have 1 hz resolution. hp1: this is the LO for the rf to if1 mixing (1st lo) . hp2: this is used to generate the 2130 Mhz signal for the sband. 250 Mhz from downstairs gets added to this to generate 2380 Mhz which then drives the sband exciter.

... We consider stars with a constant (solar) initial chemical composition. Before the Roche lobe overflow, the components evolve as single stars (see for details LPP96). ... If the mass transfer onto a normal star occurs on a time-scale ten time shorter than the thermal Kelvin-Helmholz time for this star or a compact star is engulfed by a giant companion (e.g. as a result of the kick), the common envelope (CE) stage of the binary evolution is set in (Paczynski 1976). ...

... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...

... In combining the data, it is assumed that the low resolution image better represents the short spacing data, whereas the high resolution best represents the fine structure. ... Key: out The output image. ... Key: factor The flux calibration factor. ... In practise, the calibration may not be perfect, and an extra calibration factor will be required to align the flux scales. "factor" gives the factor to scale the low resolution image to put it on the same flux scale as the high resolution image. ...
