Fig. 4
Examples of unprocessed PPak science exposures. Top: the result of drifting a template star through the central row of 21 fibers while the 15 calibration fibers are illuminated with the internal ThAr lamp. Spectra of the template star are recorded all over the detector. Bottom: a representative one-hour exposure of the galaxy UGC 4368. Again, the 15 calibration fibers are illuminated with the internal ThAr lamp. The curvature of the imaged pseudo-slit is clearly visible.
