HELP COSMOS-XID+ July 2016 ================================================================================ Description: XID+ is developed using a probabilistic Bayesian framework which provides a natural framework in which to include prior information, and uses the Bayesian inference tool Stan to obtain the full posterior probability distribution on flux estimates (see Hurley et al. 2016 for more details). This catalogue uses 24 micron detected sources from the MIPS 24 catalogue (Le Floc'h et al. 2009) as a prior list for extracting SPIRE fluxes from the Herschel Multi-Tiered Extragalactic Survey (HerMES) SPIRE maps (Oliver et al. 2012). The resulting marginalised flux probability distributions for each source, are described by the 50th, 84th and 16th percentiles. For those wanting to assume Gaussian uncertainties, take the maximum of (84th-50th percentile) and (50th-16th percentile). We note the Gaussian approximation to uncertainties is only valid for sources above: ~ 5mJy at 250 µm ~ 5mJy at 350 µm ~ 7mJy at 500 µm Column descriptions: ID - ID RA degrees Right Ascension (J2000) Dec degrees Declination (J2000) F_SPIRE_250 mJy Flux density at 250 µm (Median) FErr_SPIRE_250_u mJy Flux density at 250 µm (84th Percentile) FErr_SPIRE_250_l mJy Flux density at 250 µm (16th Percentile) F_SPIRE_350 mJy Flux density at 350 µm (Median) FErr_SPIRE_350_u mJy Flux density at 350 µm (84th Percentile) FErr_SPIRE_350_l mJy Flux density at 350 µm (16th Percentile) F_SPIRE_500 mJy Flux density at 500 µm (Median) FErr_SPIRE_500_u mJy Flux density at 500 µm (84th Percentile) FErr_SPIRE_500_l mJy Flux density at 500 µm (16th Percentile) Bkg_SPIRE_250 mJy/Beam Fitted Background of 250 µm map (Median) Bkg_SPIRE_350 mJy/Beam Fitted Background of 350 µm map (Median) Bkg_SPIRE_500 mJy/Beam Fitted Background of 500 µm map (Median) Sig_conf_SPIRE_250 mJy/Beam Fitted residual noise component due to confusion (Median) Sig_conf_SPIRE_350 mJy/Beam Fitted residual noise component due to confusion (Median) Sig_conf_SPIRE_500 mJy/Beam Fitted residual noise component due to confusion (Median) Rhat_SPIRE_250 - Convergence Statistic (ideally <1.2) Rhat_SPIRE_350 - Convergence Statistic (ideally <1.2) Rhat_SPIRE_500 - Convergence Statistic (ideally <1.2) n_eff_SPIRE_250 - Number of effective samples (ideally >40) n_eff_SPIRE_350 - Number of effective samples (ideally >40) n_eff_SPIRE_500 - Number of effective samples (ideally >40) References: Hurley, P. et al. 2016, arXiv:1606.05770 Oliver, S. et al. 2012, MNRAS 424, 1614 Le Floc’h E., et al., 2009, Astrophys.
