**Name**The names are constructed from the l and b values from the recombination line measurements. The first letter refers to our three classes of HII regions, U:ultra compact regions, C:compact, classical regions, D:diffuse regions

**l**Galactic Longitude of the recombination line measurements. If, in examining the continuum of a source, we determined that this position was off, this value was adjusted.

**b**Ditto for Galactic Latitude.

**RA**Right Ascension (J2000) calculated from the position in Galactic coordinates.

**Dec**Declination (J2000) calculated from the position in Galactic coordintes.

**V**_{LSR}The LSR velocity from the recombination line measurements.

**Ellipse l**The Galactic longitude of the fitted ellipse centroid.

**Ellipse b**The Galactic latitude of the fitted ellipse centroid.

**Size**This is the geometric mean of the semimajor and semiminor axes of the fitted ellipse.

**Semimajor**The semimajor axis of the fitted ellipse.

**Semimajor**The semimajor axis of the fitted ellipse.

**PA**The position angle of the fitted ellipse.

**V**The center of the fitted line.

**σ V**The 1σ error in the fitted line.

**T**The peak line intensity of the fitted line.

**σ T**The 1σ error in the fitted line peak intensity.

**Δ V**The FWHM of the fitted line.

**σ(Δ V)**The 1σ error in the fitted FWHM.

**T**_{ex}The excitation temperature calculated using the University of Massachusetts - Stoney Brook

^{12}CO survey.**σ T**_{ex}The 1σ error in T

_{ex}**N(**^{13}CO)Column density estimate calculated using the method in Rohlf's & Wilsons'

__Tools of Radio Astronomy__**CP**Our qualitative criteria for the confidence parameter are as follows: A: no ambiguity in position or velocity; B: either offset somewhat in position or velocity, or in a complex region of molecular gas; C: either offset in position or velocity or in a complex region, but fainter than a B source and offset further; D: diffuse emission near the correct position and velocity, but uncharacterizable due to low intensity or ambiguous morphology; E: nothing apparent at position and RRL velocity.
