Notes.

^(a)

References for distance estimates in order listed: Sanna et al. (2014); Zhang et al. (2014; 2013); Fish et al. (2003); Sato et al. (2010). All are trigonometric estimates except that for G34.3+0.1, which is a kinematic estimate.

^(b)

SOFIA deployment from Christchurch, New Zealand.

^(c)

SOFIA deployment from Palmdale, CA, USA.
