... These steps must be run on the qpoe file before the dewobble scripts are implemented. ... This is because the phase of the wobble is fixed to the space craft clock. c) Create an ASCII file with the listed obi start and end times. ... The IRAF script 'phase_repos' breaks up each obi of the qpoe file into a number of phase bins. Then a source centroid is calculated for each binned qpoe file. ... Each binned qpoe file is labelled by two indices, the obi and the phase number. ... Run phase_repos: . ...

Next: Metrology corrections Up: Astrometry data reduction Previous: Coherent integration Contents . procedure dispcorr is used to compute group delays and dispersion corrections for the data read from the .coh file.

The routine extracts from the CCF file integer arrays for RAWX, RAWY, type and yextent and a logical array showing whether the pixel has been previously identified and uplinked to the instrument for removal from the data stream. ...

The GIPSY coordinate system is implemented in terms of a collection of mostly FITS-compatible GDS descriptor items. ... The axis name is uniquely related to the physical coordinates of the pixels along the axis. ... For this position the physical coordinate is precisely defined in CRVAL i , and therefore we call this position the projection centre. ... The GIPSY coordinate system also recognizes secondary axis descriptors, which relate grid positions to a different type of physical units. ...

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. ...
