| The completeness of the Arecibo 1612 MHz survey of color-selected IRAS sources is extended to (25-12) micrometer greater than -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 1612 MHz 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 approximately equals 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. |
Target sources:
Jimenez-Esteban et al. (2005), otherwise IRAS
Comments:
Several sources were removed from the original lists as described by Jimenez-Esteban et al. (2005). In addition:
IRAS 18551+0159 (Paper I) (sidelobe detection)
IRAS 19200+1035 (Paper I) (sidelobe detection)
IRAS 22048+1138 (Paper V) (not in IRAS PSC)
IRAS 22596+1019 (Paper V) (not in IRAS PSC)
For 1665/1667 MHz entries:
The columns for the blue- and red-shifted velocities were filled with the two highest peaks listed. The leftmost and the rightmost peaks were used to calculate the radial velocity vrad and the expansion velocity vexp of the shell.
Velocity resolution: 0.1-0.5 km/s
dV_50 was taken to calculate the expansion velocity vexp
Typical position uncertainty: < 2 arcsec
