During the commissioning period in June, PAUCam collected images with a subset of the 40 Narrow Band Filters. We present here 3 examples comparing the PAUCam measured magnitudes (black squares with errors) versus the raw SDSS (fiber) measured spectrum (convolved with PAU filter) in the same object (continuous lines). Dashed lines are the same as continuous lines scaled to match the mean PAUCam measure magnitudes. The blue circles are the broad band photometric measurement from SDSS in the same object.
