Faint Object Classification and Analysis System
A general introduction to FOCAS is given. Following the introduction are detailed sections describing the data structures of the FOCAS catalogs, image files, and area description files and algorithms for detection, evaluation, classification, splitting, and matching. This manual makes reference to the FOCAS User’s Manual.
متن کاملWHY OPTICALLY–FAINT AGN ARE OPTICALLY–FAINT: THE Spitzer PERSPECTIVE
Optically–faint X-ray sources (those with fX/fR> 10) constitute about 20% of X-ray sources in deep surveys, and are potentially highly obscured and/or at high redshift. Their faint optical fluxes are generally beyond the reach of spectroscopy. For a sample of 20 optically–faint sources in CDFS, we compile 0.4–24 μm photometry, relying heavily on Spitzer. We estimate photometric redshifts for 17...
متن کاملPencil - Beam Searches for Faint
Motivated by a desire to understand the size distribution of objects in the Kuiper belt, an observing program has been conducted at the CFHT and Palomar 5-m telescopes. We have conducted pencil-beam searches for outer solar system objects to a limiting magnitude of R 26. Fields were searched using software recombinations of many short exposures shifted at diierent angular rates in order to dete...
متن کاملFaint Object Classification and Analysis System Standard Test Image Results
A set of standard test images has been analyzed using the Faint Object Classification and Analysis System (FOCAS). This paper presents an outline of the FOCAS software and algorithms followed by a summary of the results and a description of the archive containing the detail analysis. The archive is available on magnetic tape. The detailed results may be used to verify current and future distrib...
