Ratio between the sSFR of highly obscured sources and the sSFR of MS star forming galaxies, as a function of redshift. Red (green) circles represent CTKf (CTNf) sources. Filled (empty) circles represent Herschel PACS detected (undetected) sources. The MS is taken from Whitaker et al. (2012). The dashed lines shows the ratio sSFR/sSFRMS = 4 times above and below the MS, used as starbursts and quiescent galaxy definition. The blue dotted (dashed) curves mark the sSFR/sSFRMS observability limit of the Herschel PEP survey in COSMOS, obtained for a Log (M) = 11.5 (10.5), using the Seyfert-2 template of Polletta et al. (2007).
