Multi - color Classification in the Calar Alto Deep Imaging Survey ⋆
We use a multi-color classification method introduced by Wolf, Meisenheimer & Röser (2000) to reliably identify stars, galaxies and quasars in the up to 16-dimensional color space provided by the filter set of the Calar Alto Deep Imaging Survey (CADIS). The samples of stars, galaxies and quasars obtained this way have been used for dedicated studies which are published in separate papers. The c...
متن کاملAstraLux: the Calar Alto Lucky Imaging Camera
AstraLux is the Lucky Imaging camera for the Calar Alto 2.2-m telescope, based on an electron-multiplying high speed CCD. By selecting only the best 1-10% of several thousand short exposure frames, AstraLux provides nearly diffraction limited imaging capabilities in the SDSS i’ and z’ filters over a field of view of 24×24 arcseconds. By choosing commercially available components wherever possib...
متن کاملThe evolution of galaxy clustering since z = 1 from the Calar Alto Deep Imaging Survey ( CADIS )
We present results from an investigation of the clustering evolution of field galaxies between a redshift of z ∼ 1 and the present epoch. The current analysis relies on a sample of ∼ 3600 galaxies from the Calar Alto Deep Imaging Survey (CADIS). Its multicolor classification and redshift determination is reliable up to I = 23 mag. The redshift distribution extends to z ∼ 1.1, with formal errors...
متن کاملThe Night-sky at the Calar Alto Observatory
We present a characterization of the main properties of the night-sky at the Calar Alto observatory for the time period between 2004 and 2007. We use optical spectrophotometric data, photometric calibrated images taken in moonless observing periods, together with the observing conditions regularly monitored at the observatory, such as atmospheric extinction and seeing. We derive, for the first ...
متن کاملThe Calar Alto Deep Imaging Survey: K-band Galaxy Number Counts
We present K-band number counts for the faint galaxies in the Calar Alto Deep Imaging Survey (CADIS). We covered 4 CADIS fields, a total area of 0.2 deg, in the broad band filters B, R and K. We detect about 4000 galaxies in the K-band images, with a completeness limit of K = 19.75mag, and derive the K-band galaxy number counts in the range of 14.25 < K < 19.75mag. This is the largest medium de...
