Explanatory Supplement of the ISOGAL - DENIS Point Source Catalogue ⋆ , ⋆ ⋆
We present version 1.0 of the ISOGAL–DENIS Point Source Catalogue (PSC), containing more than 100,000 point sources detected at 7 and/or 15 µm in the ISOGAL survey of the inner Galaxy with the ISOCAM instrument on board the Infrared Space Observatory (ISO). These sources are cross-identified, wherever possible, with near-infrared (0.8—2.2 µm) data from the DENIS survey. The overall surface cove...
متن کاملHerMES: point source catalogues from deep Herschel-SPIRE observations
We describe the generation of single-band point source catalogues from submillimetre Herschel-SPIRE observations taken as part of the Science Demonstration Phase of the Herschel Multi-tiered Extragalactic Survey (HerMES). Flux densities are found by means of peak finding and the fitting of a Gaussian point-response function. With highly confused images, careful checks must be made on the comple...
متن کاملHerMES: point source catalogues from Herschel-SPIRE observations II
The Herschel Multi-tiered Extragalactic Survey (HerMES) is the largest Guaranteed Time Key Programme on the Herschel Space Observatory. With a wedding cake survey strategy, it consists of nested fields with varying depth and area totalling ∼380 deg. In this paper, we present deep point source catalogues extracted from HerschelSPIRE observations of all HerMES fields, except for the later additio...
متن کاملBiases in the polarization position angles in the NVSS point source catalogue
We have examined the statistics of the polarization position angles determined for point sources in the NRAO-VLA sky survey (NVSS) and find that there is a statistically significant bias toward angles which are multiples of 45 degrees. The formal probability that the polarization angles are drawn from a uniform distribution is exponentially small. When the sample of those NVSS sources with pola...
متن کاملSPIRE Point Source Photometry . within the Herschel ⋆ Interactive Processing Environment ( HIPE )
The different algorithms appropriate for point source photometry on data from the SPIRE instrument on-board the Herschel Space Observatory, within the Herschel Interactive Processing Environment (HIPE) are compared. Point source photometry of a large ensemble of standard calibration stars and dark sky observations is carried out using the 4 major methods within HIPE: SUSSEXtractor, DAOphot, the...
