Detection rate

 \citet{2003ApJ...583..334H} detected the [O I] 6300 Ang line in emission in a little more than half of the objects and all our candidates are on that list. 

Discussion

We begin the discussion by looking at the two sources where the jet was clearly detected.

DF Tau

DF Tau is a
\citet{2004ApJ...609..261H} observed the jet of DF Tau with low-resolution slitless spectroscopy with STIS. They see jet and counterjet at a position angle of 127 degrees, but the binary is not resolved and it remains unclear if we see one jet from both components each or if both are launched from the same component of the binary. For our observations , the PA of the slit was XXX TAB XXX thus, 
Notes that still need to be worked into the text:
DF Tau jet knows http://adsabs.harvard.edu/abs/2004ApJ...609..261H with inclinations angle - means we can use that here for calculate deprojected velocity.
