Abstract:
The completeness of the Arecibo 1612 MHz survey of color-selected/IRAS
sources (see references) is extended to (25-12)µm>-0.7. In addition
(1) most IR sources with spectral types normally associated with OH/IR
stars and colors outside the coverage of the original survey have been
examined; (2) most ambiguous observations during the survey have been
reobserved: (3) most single peaked sources have been reexamined, and
17 found with second peaks. We report 39 new 1612MHz detections, of
which 34 are original. These are also surveyed in the mainlines.
Analysis of the complete flux-limited survey confirms the existence of
a longitude sensitivity effect in the detection of sources, which
reduces the total number detected by ∼4%. This analysis sets an upper
limit of 16%, on the proportion of a color-selected sample that may be
identified with carbon stars and/or star-formation regions.
