Calibration Spectra in Commissioning

Blue Circles= SDSS g,r,i broad band (model magnitudes) Squares= PAU narrow bands (preliminary/incomplete) Continuous line= SDSS spec (raw, filtered to PAU narrow bands) Dashed line (with shaded errors)= SDSS spec scaled to match PAU
This is a sample sequence of (preliminary/incomplete) PAU data taken during last night of commissioning in June 2015. Here we compare the PAU Narrow Band measurements with SDSS Spectra to validate the camera and data reduction.
This a first pass. There is room for improvement/optimization in the data reduction processing/calibration to eliminate some remaining outliers. However the spectro-photometric system of PAU seems to behave as expected.
