Next: Fringe correction Up: Special Processing Options Previous: Sky Illumination Corrected . A third method to account for illumination problems in the flat fields is to remove the large scale pattern from the flat field itself. This is useful if there are no reasonable blank sky calibration frames and the astronomical exposures are evenly illuminated but the flat fields are not. This is done by smoothing the flat field frames instead of blank sky frames. ...

UVFXT (to fix timestamps on GMRT uv data files within AIPS) =========================================================== To correct GMRT visibilites with timestamps near the beginning of the integration period, instead of middle. For example, for 16.9 s integrations, move timestamps on all uv data points forward by 7.4 s, (i.e. to centre of 16.9 s from the centre of the initial 2.1 s integration), and rotate u,v,w coordinates forward. ...

The main steps in the reduction of NIR spectroscopic data are flat-field correction, subtraction of sky emission, wavelength calibration, correction for telluric absorption and correction for optical system plus detector efficency. ... Sky subtracted frames are corrected computing analitically the tilt angle from the instrumental calibration parameters or directly measuring it from the data. ... The same procedures are applied to the reference stars frames to obtain the calibration spectra. ...

Next: Introduction . ... A spike immunity method of digital integrating radiometer signals in the jamming environment is described. ... The purpose of the method is real-time signal processing, and the basic is an alternative selection of the least offset signal estimation using nonparametric "Nearest Neighbor" rule. ... The additive spike-like jam makes the "tails" of the distribution "heavier" which leads to different offsets for linear and rank mean estimation on the integrating interval. ...
