Finds the brightest spectrum in an image.
| in | spectral image with spectra | |
| offset | the diff. between pos. and neg. spectra | |
| shadows | the spectral shadows | |
| min_bright | min. bright. required for a spectrum | |
| orient | 1 for vertical spec. 0 for horizontal ones | |
| pos | the computed spectrum position (1->npix) |
Finds the brightest spectrum in an image by collapsing the image orthogonally to the spectrum orientation. Spectra are assumed to be horizontal for orient==0, vertical for 1
