How does the quality of the ERO data compare to GALEX observations so far, and to the planned complete mission?
The ERO imaging data quality should be typical for GALEX observations so far. The satellite performance has been stable, and the pipeline has been revised twice to account for on-orbit performance. We anticipate that further improvements in the pipeline may improve the PSF and flat-field moderately, and may handle detector artifacts more automatically. The catalogues are expected to improve substantially in future data releases. A principle deficiency in the early pipeline is the handling of the most extended sources, which tend to be shredded by the detection algorithms. Faint sources near the confusion limit will probably require refined processing to achieve the theoretical sensitivity limits. In particular, the ERO spectroscopic products (catalogues, extracted spectra) have received substantially less attention than the images, and we expect significant improvements in future releases.
