Only the //J"// = 12.5 and 15.5 transitions near 215.05 and 262.81 GHz appear to be unblended. While this is fine for a tentative detection, it is too little for us to qualify for a definitive detection. | Dedicated observations of CW Leonis with the ARO 12 m dish at Kitt Peak as well as observations (dedicated and from a line survey) with the ARO SMT in the regions of the <sup>2</sup>Π<sub>3/2</sub>, //J"// = 7.5, 12.5, 15.5, and 16.5 transitions of SiP.

The authors derive peak abundances only slightly lower than CP and even slightly higher than PN, but somewhat closer to the star.\\ |
