Calibration Spectra in Commissioning
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.
