VizieR Online Data Catalog: Herschel counterparts of SDC (Peretto+, 2016)

The goal of this paper is to identify which of the clouds from the Spitzer Dark Cloud catalogue (Peretto & Fuller, 2009, Cat. J/A+A/505/405) are real, which are artefacts. For this we used Herschel Hi-GAL (Molinari et al., 2010PASP..122..314M) column density maps and search for spatial associations between Spitzer Dark Cloud and Herschel column density peaks.

Description: This table provides some of the key properties of the Spitzer Dark Clouds that we estimated using the Herschel data and used to disentangle between real and spurious clouds. For each cloud of the Peretto & Fuller (2009, Cat. J/A+A/505/405) catalogue we give the cloud name, the cloud equivalent radius, the average Herschel column density within the boundaries of the SDCs, the average Herschel column density immediately outside the boundary of the SDCs, the Herschel column density noise at the position of the SDC, the Herschel column density peak within the boundaries of the SDCs, the value for criterion c1, the value for criterion c2, the value for criterion c3, and a tag that indicates if the cloud has been identified as real by our automated detection scheme based on the values of c1 and c2. This tag can take a number of values. These are: 'y' for yes; n for no; 'sat' for a SDC entirely located in a saturated portion of the Herschel images; 'ysat' for a cloud that is considered real despite being partially saturated; 'out' for a SDC that is not covered by Herschel images; 'yout' for a cloud that is considered real despite being partially covered by Herschel images; 'nout' for a cloud considered spurious despite being partially covered by Herschel images. Also, note that the column referring to the equivalent radius Req is the same quantity as the one quoted in Table 1 column 11 of Peretto & Fuller (2009, Cat. J/A+A/505/405). However, these latter values should be discarded since a mistake has been found in the calculation of the equivalent radius. Only the new values, the ones provided in Table 1 column 2 of this paper should be considered.
