1. A Region mask for a radial profile in concentric, elliptical annuli
... select cursor and ellipse . ... The three mouse buttons have been redefined as: . ... i.e. , the axial ratio and orientation of the ellipse are fixed, only adding (or removing) ellipses of different area is possible. obtain different annuli by placing the mouse at some distance from the ellipse and clicking on the MIDDLE button to produce equally spaced, concentric ellipses towards the mouse position. ... Note: &! means ``and not''; i.e., an elliptical annulus rather than a solid ellipse. ...

3. Order Definition
... The first of the equations defines the position of the spectral orders, m , in the raw image, while the second equation gives, for each order, the dispersion relation in one dimension. ... where the coefficients are computed using least squares techniques on a grid , i.e. sample number and line number of points located within the spectral orders of the image. These points in the grid are found automatically by an order--following algorithm, normally using the FLAT or STD image. ...

11. Rotation range
... This document and the attached postscript figure document an analysis that I did to determine the optimum midpoint and required ranges for both the rotator and azimuth for the 2.5 M telescope. ... I simulate a series of drift scans on the sky for tracks that cover the northern survey area. These tracks cover the range in survey latitude of -60 to +60 degrees, spaced by 10 degrees. ... Along each track the azimuth, elevation, and position angle of the CCD is computed at 1 minute intervals. ...
