... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. 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. ...

Next: The Echelle Relation Up: Wavelength Calibration Previous: Wavelength Calibration . A preliminary step to the wavelength calibration consists of extracting the orders of the WLC image which can then be used to determine the dispersion relation in two steps: . ... Both methods are based on the echelle relation and therefore are not applicable if the disperser is not an echelle grating, as it is the case for EFOSC which involves a grism disperser. ...

... epevents (epevents-6.42.2) [?? ... A pattern analysis is made which yields four distinctive parameters: the number of pixels in the structure, the running pattern number within a frame, the pattern orientation (zero for singles and unresolved patterns; otherwise a three digit code, with the last digit specifying the orientation of the pattern and the first two the position of the pixel on the pattern ) and the distance (in pixels ) to neighbouring ...
