That is the mapping between the space wavelength, spectral order and the space sample x , line y in the raw image. ... Sections and describe the solution of this mapping. The second step in the reduction, described in Section , is to estimate the image background. ... In the rest of this Section the algorithms used in each step of the reduction are described. ...
