... Task uvlin behaves somewhat like a copying program, taking an input dataset (selecting, calibrating and performing Stokes conversion, as appropriate), performing the continuum subtraction, and writing out a resultant dataset. ... vis : The name of the input dataset. select : The subset of data to select. line : The normal line parameter. chans : This gives the set of channels to be used in the fitting process. ... Normally you will want to write the line data (the data after continuum subtraction). ...

SKA ­ TDT Group On Phase Computation during Folding C.Baffa, E.Giani January 2014 The last part of pulsar search algorithm, as in the SKA TDT group approach, is the verification and optimization of pulsar parameters candidates identified in the previous phases. ... As the phase errors are expressed as fractions of the full period (in our case 44 measurement of 50 s), it is evident that the maximum integration time compatible with single precision phase computation is very short. ...

The visibility amplitude bias (there is also a closure phase bias, but this one is nominally corrected by the raw data averaging pipeline) is related to non-Poisson detector statistics due to after-pulsing, and to fixed pattern noise due to non-linearities in the modulation stroke. We determine the bias using so-called incoherent scans, which record data even though the delay lines are deliberately set away from the white light fringe. ... Averaging triple products.. ...

The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... There is a need to calculate the fractional exposure FRACEXP column entries in the CCD specific exposure extensions (see [ 2 ] and SSC_LUX_TN_0038) per frame which will be addressed by higher level SAS tasks for the computation of exposure times or exposure maps. ... A problem arises when comparing these counters with the number of events in the actual CCD specific events list: counters are given every CYCLEs and they come per quadrant, i.e. not per CCD . ... Mode dependent livetime factor FC0 . ...

... This review presents the results of Scenario Machine computations aimed at the population synthesis of different types of binary stars in our Galaxy and another galaxies. They demonstrate the ability of this method to make an important gross analysis of the modern scenarios for binary evolution, as well as to give interesting qualitative and quantitative predictions which can be checked observationally. ... The future development of the method can be considered from two different points of view. ...
