Abstract:
Since the advent of Submillimetre Common-User Bolometer Array (SCUBA)
on the James Clerk Maxwell Telescope (JCMT), a series of complementary
surveys has resolved the bulk of the far-infrared extragalactic
background into discrete sources. This has revealed a population of
heavily dust-obscured sources at high redshift (z>1) undergoing an
intense period of massive star-forming activity with inferred star
formation rates of several hundred to several thousand solar masses
per year. Taken together, these existing surveys cover a total area of
460arcmin2 to a range of depths, but combining the results has
hitherto been complicated by the fact that different survey groups
have used different methods of data reduction and source extraction.
In this paper, we re-reduce and re-analyse all of the blank-field
surveys to date in an almost identical manner to that employed in the
'SCUBA 8-mJy Survey'. Comparative source catalogues are given which
include a number of new significant source detections as well as
failing to confirm some of those objects previously published. These
new source catalogues have been combined to produce the most accurate
number counts to date from 2 to 12.5mJy.
Description:
The raw data for the 'CUDSS', the 'HFFS', and the 'Hubble Deep Field
Survey' (pencil beam only) were downloaded from the CADC archive. The
data were then fully reduced using the same Interactive Data Language
(IDL)-based reduction routines employed in the 'SCUBA 8-mJy Survey'.
