Autoflip ensures that a newly loaded image containing FITS WCS information will be oriented so that "north is up", that is, so that increasing "cdelt1" is toward the left and increasing "cdelt2" is in the upward direction. ... If the CD1_1 or CDELT1 parameter (in that order) is positive, then the image is flipped in x. If the CD2_2 or CDELT2 parameter (in that order) is positive, then the image is flipped in y. If none of these parameters exist, then no auto-flipping is performed. ...

LonGSp is a near-infrared grating spectrometer, designed for the 1.5 m Italian Infrared Telescope T.I.R.GO. ... The sky-projected pixel size along the slit is 1.73" and the maximum slit length is about 70., this means that only a 40 pixels stripe of the array is used. ... Read-out and control electonics are the same of ArNICa , based on the IRL System 2 developed by Infrared Laboratories (Tucson - AZ), with the necessary alteration to control slits and grating and for handling spectroscopic data. ...
