  The Transit Ephemeris Refinement and Monitoring Survey (TERMS) is a project
which aims to detect transits of intermediate-long period planets by refining
orbital parameters of the known radial velocity planets using additional data
from ground based telescopes, calculating a revised transit ephemeris for the
planet, then monitoring the planet host star during the predicted transit
window. Here we present the results from three systems that had high
probabilities of transiting planets: HD 9446 b & c, HD 43691 b, & HD 179079 b.
We provide new radial velocity (RV) measurements that are then used to improve
the orbital solution for the known planets. We search the RV data for
indications of additional planets in orbit and find that HD 9446 shows a strong
linear trend of 4.8$\sigma$. Using the newly refined planet orbital solutions,
which include a new best-fit solution for the orbital period of HD 9446 c, and
an improved transit ephemerides, we found no evidence of transiting planets in
the photometry for each system. Transits of HD 9446 b can be ruled out
completely and transits HD 9446 c & HD 43691 b can be ruled out for impact
parameters up to b = 0.5778 and b = 0.898 respectively due to gaps in the
photometry. A transit of HD 179079 b cannot be ruled out however due to the
relatively small size of this planet compared to the large star and thus low
signal to noise. We determine properties of the three host stars through
spectroscopic analysis and find through photometric analysis that HD 9446
exhibits periodic variability.
