SVO Calar Alto CAFOS Direct Imaging First Data Release archive

This data server provides access to the catalogue of detections built from the images taken with the CAFOS (Calar Alto Faint Object Spectrograph) instrument at the 2.2m telescope at Calar Alto Observatory between September 2012 and June 2019 in the Sloan photometric bands (griz).

The products of this first data release are described in Cortés-Contreras et al. 2023. It includes:

• Reduced and astrometrically calibrated images (See Calar Alto archive).
• A detection catalogue. It provides accurate coordinates, detection identifier, image identifier and url of the associated reduced image, PSF calibrated photometry and related quality flags together with the reference catalogue used for the calibration, morphometric parameters (elongation, ellipticity, FWHM), signal to noise ratio, spread parameter from model-fitting, and epoch of observation.
