... This task takes an OM OSW source list, with source positions in pixels, and converts to sky coordinates. These sky coordinates are then used to produce a sky coordinate image. The task requires the user to enter the name of an OSW source list and its corresponding OSW image. ... The tangent plane coordinates are then converted to sky coordinates. ... The algorithm sets up a grid of offsets in the x and y directions to be used to match up stars in the source list to those in the catalogue. ...

... 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. ...

It seems that every time I try to correct for a pointing error, I have to figure out the sign of the pointing error as reported by the various routines. The pointing error is computed using the heiles calibration scans and by using the turret scans. ... The center of the pattern is the "computed" position of the source using the ra,dec transformation to az,za and any current pointing model. ... X0, Y0 are reported as the error. ... So for turret scans, Add the az,za error to the pointing model. ...
