We present a catalog of compact sources derived from the QUaD Galactic Plane Survey .
The survey covers \sim 800 square degrees of the inner galaxy ( |b| < 4 ^ { \circ } ) in Stokes I , Q , and U parameters at 100 and 150 GHz , with angular resolution 5 and 3.5 arcminutes respectively .
505 unique sources are identified in I , of which 239 are spatially matched between frequency bands , with 50 ( 216 ) detected at 100 ( 150 ) GHz alone ; 182 sources are identified as ultracompact H ii ( UC H ii ) regions .
Approximating the distribution of total intensity source fluxes as a power-law , we find a slope of \gamma _ { S, 100 } = -1.8 \pm 0.4 at 100 GHz , and \gamma _ { S, 150 } = -2.2 \pm 0.4 at 150 GHz .
Similarly , the power-law index of the source two-point angular correlation function is \gamma _ { \theta, 100 } = -1.21 \pm 0.04 and \gamma _ { \theta, 150 } = -1.25 \pm 0.04 .
The total intensity spectral index distribution peaks at \alpha _ { I } \sim 0.25 , indicating that dust emission is not the only source of radiation produced by these objects between 100 and 150 GHz ; free-free radiation is likely significant in the 100 GHz band .
Four sources are detected in polarized intensity P , of which three have matching counterparts in I .
Three of the polarized sources lie close to the galactic center , Sagittarius A* , Sagittarius B2 and the Galactic Radio Arc , while the fourth is RCW 49 , a bright H ii region .
An extended polarized source , undetected by the source extraction algorithm on account of its \sim 0.5 ^ { \circ } size , is identified visually , and is an isolated example of large-scale polarized emission oriented distinctly from the bulk galactic dust polarization .
