- Description:
- INAF-OATs SVAS Educational Images SIAP service. Le Stelle Vanno A Scuola (SVAS) proposes a modern tool to support teaching of astronomy, through the study and experimentation of its observation methods. SVAS offers to schools and teachers a remote laboratory with which carry out real observation sessions, managed in real time by the students under the supervision of the teacher, in the classroom, and of an astronomer, at the OATs, thanks to the telematic link between the school and the observatory. Students and teachers experience real astronomical observations, through the interactive participation to the different steps of planning, observing and acquiring the data. The project is addressed to 13-18 yr students. Every observation is previously planned together with the teachers, according to age and curriculum of the students, with the aim to maximize the results. The observing activity, lasting about 90 minutes and led by an astronomer of the OATs, can be done during the morning (observation of the Sun) or in the evening (observation of stars, nebulae, clusters and galaxies). SVAS involves the Astronomical Observatory of Trieste (OATs), the school (of every level) and the University of Trieste. SVAS is supported by the Consorzio per l’Incremento degli Studi e delle Ricerche dei Dipartimenti di Fisica e Astronomia dell’Università di Trieste and by the Ministero dell'Istruzione, dell'Università e della Ricerca.

- Title:
- Laurino et al 2011 Catalog of WGE photometric redshifts for SDSS candidate qsos and galaxies

- Description:
- The Sloan Digital Sky Survey (SDSS) has observed more than a quarter of the sky over eight years of operations, obtaining multicolor photometry and spectroscopy for ~ 1 million of galaxies. A catalog of photometric redshifts for ~ 2 millions quasars with magnitude r < 20.7 extracted from the SDSS DR7 dataset (D'Abrusco et al, 2009) is provided here. The photometric redshifts and the uncertainty of the estimates for each sources have been calculated using the Weak Gated Expert (WGE) method. The WGE (Laurino et al., submitted to MNRAS) is based on the exploitation of the spectroscopic redshifts for a subset of photometric sources and derives photometric redshifts through a combination of data mining techniques. This method can be applied to different classes of extragalactic sources and is scalable. A set of observational parameters used for the evaluation of photometric redshifts, the estimated photometric redshifts values and some of the most common observational parameters retrieved from the SDSS database have been included in the catalog for the sake of simplicity.

- Description:
- The Sloan Digital Sky Survey (SDSS) has observed more than a quarter of the sky over eight years of operations, obtaining multicolor photometry and spectroscopy for ~ 1 million of galaxies, and the GALEX survey is the ultraviolet counterpart of the SDSS. A catalog of photometric redshifts (evaluated using optical and ultraviolet photometry) for ~150000 candidate quasars with magnitude r < 20.7, extracted from the SDSS DR7 dataset (D'Abrusco et al, 2009) and with GALEX counterparts, is provided here. The photometric redshifts and the uncertainty of the estimates for each source have been calculated using the Weak Gated Expert (WGE) method.

- Description:
- The Sloan Digital Sky Survey (SDSS) has observed more than a quarter of the sky over eight years of operations, obtaining multicolor photometry and spectroscopy for ~ 1 million of galaxies. A catalog of photometric redshifts for ~ 32 millions galaxies with magnitude r < 21 extracted from the SDSS DR7 dataset (D'Abrusco et al, 2009) is provided here. The photometric redshifts and the uncertainty of the estimates for each sources have been calculated using the Weak Gated Expert (WGE) method.

- Title:
- Planck Early Release Cold Core Catalog @ IA2
- Short Name:
- PlanckERCSCecc
- Date:

- Publisher:
- IA2
- Description:
- The Planck Early Release Compact Source Catalogue (ERCSC) is a list of all high reliability sources, both Galactic and extragalactic, derived from the first sky coverage. The data that went into this early release comprise all observations undertaken between 13 August 2009 and 6 June 2010, corresponding to Planck operational days 91-389. Since the Planck scan strategy results in the entire sky being observed every 6 months, the data considered in this release correspond to more than the first sky coverage. The source lists have reliability goals of 90% across the entire sky and > 95% at high Galactic latitude. The goals on photometric accuracy are 30% while the positional accuracy goal translates to a positional root mean square (RMS) uncertainty that is less than 1/5 of the beam full width at half maximum (FWHM). ref.: "Planck Early Results: The Early Release Compact Source Catalog" (ADS BibCode: 2011arXiv1101.2041P)
