a Position of the H2 outflow source if one is listed in Col. 4. Otherwise, the position of the brightest knot in the flow is given (enclosed in brackets). Note that the well-known sources of the HH 1/2, HH 83 and V380-Ori-NE flows were not identified in our tables of Spitzer protostars or disc-excess sources.
b Most likely H2 outflow source from the Spitzer photometry together with the spectral index, $\alpha $. Just a question mark means there is no obvious H2 flow source candidate.
c 850 $\mu $m dust core coincident with the H2 outflow source (from Nutter & Ward-Thompson 2007). The source must lie within a 14 $^{\prime\prime}$ radius (the JCMT beam at 850 $\mu $m) of the core position given by Nutter & Ward-Thompson in their Table A.1. ''Emission'' or ``undetected'' means that no core appears in their table. However, ``emission'' means that the source identified in Col. 4 is associated with diffuse 850 $\mu $m emission (surface brightness >100 mJy beam-1, which is roughly equivalent to 5$\sigma $); a question mark means there are cores (or emission) in the vicinity which could be associated with the outflow or its source; ``no obs'' means that the outflow is outside the bounds of the SCUBA map. The core size (major/minor axis dimensions), Ap850, and integrated flux, I850, are given for each core; F850 is the flux, in Jy beam-1, measured towards each IRS source (not necessarily the peak flux of the associated core).
d Same as for the 850 $\mu $m cores, but for cores identified from our analysis of the 1200 $\mu $m observations of Stanke et al. (in prep.). In this case the source must lie within 11 $^{\prime\prime}$ of the core centroid; ``emission'' corresponds to a surface brightness >75 mJy beam-1 ($\sim $$5\sigma$). The values given in brackets in the Ap1200 column are the orientation of the core major axis (this information was not available for the 850 $\mu $m cores).
e Entire length (L) of all H2 knots (in both lobes), or the distance from the source to the most distant H2 knot if only one flow lobe is identified; opening angle ($\theta$) measured from a cone centred on the outflow source that includes all H2 features in the flow; position angle (PA) measured east of north.
f Associated HH objects, if any are known.
