Next: Three-dimensional Data Analysis in IRAF and ZODIAC+ . ... A data analysis system has been developed at SRON, which has been designed to allow rigorous control of the quality of its processed data products. ... This means recording all parameters of all steps which lead to the establishment of the final data products (Figure 1 ). ... Figure: A processing pipeline is a sequence of tasks with several input/output files and parameters, which pass data from one task to the next. ...

... 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. ...

... The following algorithm shows the rough details of these calculations. ... Similarly the energy selection region for the reflection order of the output matrix is converted to the array called banana. // analyze the exposure maps within the spatial selection regions FOREACH node FOREACH b = dispersion channel of node src.exposure[ node ,b] = EXPMAP node [b] summed over src.spans[ node ,b] bkg.exposure[ node ,b] = EXPMAP node [b] summed over bkg.spans[ node ,b] D = EXPMAP ...
