J/ApJS/93/549       Arecibo 1612 MHz survey supplement (Lewis 1994)

Supplement to the Arecibo 1612 MHz survey of color-selected IRAS sources Lewis B.M. <Astrophys. J. Suppl. Ser. 93, 549 (1994)> =1994ApJS...93..549L
ADC_Keywords: Radio sources Keywords: infrared: stars - radio lines: stars - stars: AGB and post-AGB surveys 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.
