Abstract:
We present the final results from the Arecibo Observatory OH megamaser
survey. We discuss in detail the properties of the remaining 18 OH
megamasers detected in the survey, including three redetections. We
place upper limits on the OH emission from 85 nondetections and
examine the properties of 25 ambiguous cases for which the presence or
absence of OH emission could not be determined. The complete survey
has discovered 50 new OH megamasers (OHMs) in (ultra)luminous infrared
galaxies ([U]LIRGs), which doubles the sample of known OHMs and
increases the sample at z>0.1 sevenfold.

Note (1): This marginal OH detection (3.4σ; Dickey et al.,
1990AJ....100.1457D 1990AJ....100.1457D) was undetectable at Arecibo because of
standing waves produced by its strong continuum.
Note (2): If no continuum source lies within 30" of the IRAS coordinates,
an upper limit of 5.0mJy is listed.
Note (3): Spectral classifications as follows:
S1 = Seyfert type 1
S2 = Seyfert type 2
H = HII region (starburst)
L = low-ionization emission region (LINER)
