Number counts in the K-band, from HUGS and from the recent literature (see text for full references for the previous surveys). In blue are the HUGS counts corrected for incompleteness assuming a faint galaxy size distribution spanning the range r_hl = 0.1–0.3 arcsec. In red we show the counts that are derived assuming point-like sources. Recent results from the literature are also shown: SSDF: Minowa et al. (2005), HDFS: Labbé et al. (2003), KDS: Moustakas et al. (1997), UDS: Cirasuolo et al. (2010), WHTDF: Cristóbal-Hornillos et al. (2003), HWDF: Huang et al. (1997), POWIR: Conselice et al. (2008), U.VISTA DR1: McCracken et al. (2012), GOODS: Grazian et al. (2006).
