Abstract:
We present the first data release of the James Clerk Maxwell Telescope
Plane Survey (JPS), the JPS Public Release 1. JPS is an 850-µm
continuum survey of six fields in the northern inner Galactic plane in
a longitude range of l=7°-63°, made with the Submillimetre
Common-User Bolometer Array 2. This first data release consists of
emission maps of the six JPS regions with an average pixel-to-pixel
noise of 7.19mJy/beam, when smoothed over the beam, and a compact
source catalogue containing 7813 sources. The 95 per cent completeness
limits of the catalogue are estimated at 0.04Jy/beam and 0.3Jy for the
peak and integrated flux densities, respectively. The emission
contained in the compact source catalogue is 42±5 per cent of the
total and, apart from the large-scale (greater than 8 arcmin)
emission, there is excellent correspondence with features in the
500-µm Herschel maps. We find that, with two-dimensional matching,
98 ± 2 per cent of sources within the fields centred at l=20°,
30°, 40° and 50° are associated with molecular clouds,
with 91±3 per cent of the l=30° and 40° sources associated
with dense molecular clumps. Matching the JPS catalogue to Herschel
70-µm sources, we find that 38±1 per cent of sources show
evidence of ongoing star formation. The JPS Public Release 1 images
and catalogue will be a valuable resource for studies of star
formation in the Galaxy and the role of environment and spiral arms in
the star formation process.
Description:
We present here the first complete public release of data, JPS Public
Release 1 (JPSPR1), and the compact source catalogue (CSC) extracted
from the James Clerk Maxwell Telescope (JCMT) Plane Survey (JPS).
JPS is a targeted, yet unbiased, survey of the inner Galactic plane in
the longitude range 7°<l<63° using the wide-field sub-mm-band
bolometer camera, the Submillimetre Common-User Bolometer Array 2
(SCUBA-2) at 850um with an angular resolution of 14.5 arcsec.
