Query: A Pilot Imaging Line Survey of RW LMi and IK Tau Using the Expanded Very
  large Array   We report on a pilot imaging line survey (36.0 - 37.0 GHz, with ~1 km/s
spectral channels) with the Expanded Very Large Array for two asymptotic giant
branch stars, RW LMi (= CIT6, which has a carbon-rich circumstellar envelope)
and IK Tau (= NML Tau, with an oxygen-rich circumstellar envelope). Radio
continuum emission consistent with photospheric emission was detected from both
stars. From RW LMi we imaged the HC3N (J = 4 -> 3) emission. The images show
several partial rings of emission; these multiple shells trace the evolution of
the CSE from 400 to 1200 years. SiS (J = 2 -> 1) emission was detected from
both RW LMi and IK Tau. For both stars the SiS emission is centrally condensed
with the peak line emission coincident with the stellar radio continuum
emission. In addition, we have detected weak HC7N (J = 32 -> 31) emission from
RW LMi.
