* Once you have identified the lines in one aperture, repeat for every nth pixel (probably every 5th pixel is fine, the tilt is about 0.6 06 pixels per pixel) using '''reidentify'''.
* Run '''fitcoords''' on the database produced by reidentify
* Run '''transform''' on the image using the fitcoords database to produce a wavelength-calibrated, rectified 2D arc.
