Classifying Objects by Medium-Band Observations
- a spectrophotometric 17-filter survey -


The COMBO-17 survey:

  • has imaged 1 square degree of sky in 17 optical filters using the Wide Field Imager at the MPG/ESO 2.2-m telescope at La Silla, Chile. 

  • found ~25000 galaxies and ~300 QSOs with redshift errors of dz/(1+z) ~ 0.02, as well as ~5000 stars and ~30 white dwarfs

  • has deep and sharp R-band data for exploration of weak gravitational lensing.
