cds-question@unistra.frinfrared-sourcesradio-astronomyWe present the results of 1612MHz observations conducted at the Arecibo Observatory of 571 color-selected sources from the IRAS Point Source Catalog. Of these sources we detect 132, 113 for the first time. This is the third part of an Arecibo survey of color-selected IRAS sources. The earlier two parts together detected a total of 268 sources of 1612MHz emission. An analysis of the properties of the OH/IR stars detected in all three parts of the survey is included. In particular we compute the limiting 1612MHz peak flux of the entire survey to be ~40mJy. The correlation between the IRAS infrared fluxes and the 1612MHz flux of the 132 sources detected in part III of the survey is smaller than that found in the earlier parts of the survey. This is to be expected from the intrinsic variability of OH/IR stars and the longer time gap between the 1612MHz observations and the IRAS measurements. We identify a subset of 54 stars as being near the tangent point of the galactic rotation curve. Using the kinematical distances to these stars we find that the efficiency of momentum transfer varies exponentially with the (25-12){mu}m color, consistent with the stellar outflow being driven by radiation pressure. Further the IR pump efficiency increases with increasing optical depth of the circumstellar shell, as expected for radiative pumping. The bolometric luminosity function is found to decrease sharply above L_Bol_=5600L_{sun}_, and the 1612MHz luminosity function shows a corresponding falloff above L_1612_=1.8x10^-8^L_{sun}_. We also find direct confirmation of the expectation that sources with large expansion velocity are more luminous than sources with small expansion velocity.1993ApJS...89..189Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/89/189CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS Point Source Catalogue, Version 2.0 (IPAC 1986)J/A+AS/90/327 : IRAS Point Source 1612MHz OH survey (te Lintel Hekkert+ 1991)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/89/189https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/89/189http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/89/189https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/89/189https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/89/189http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/89/189GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/89/189/table1 (Detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/89/189/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/89/189/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/89/189/table1?GETtext/xml+votable180.050000true17.31435930.6354080.005555555555555556Cone search capability for table J/ApJS/89/189/table2 (Non-detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/89/189/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/89/189/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/89/189/table2?GETtext/xml+votable180.050000true1.21390.80790.0055555555555555565/3585 3588 3600 3613 3650 7583 7654 7676 7678 6/118 342 461 511 862 1040 1050 1054 1061 1074 1088 1102 1111 1125 1136 1156 1159 1168 1169 1179 1217 1244 1285 1293 1539 1542 1561 1575 1578 2110 2224 5647 6251 6681 8532 10311 12300 12440 12576 12578 12690 12706 12729 12733 12777 12800 12817 12833 12834 12839 12854 12889 12932 12933 12936 12938 12944 12946 12954 12955 12957 12960 12962 12966 12968 12969 12971 12980 12981 12982 12988 12991 13011 13016 13025 13026 13030 13033 13034 13035 13038 13040 13048 13051 13063 13072 13077 13108 13113 13134 13154 13159 13161 13163 13191 13192 13198 13207 13211 13216 13224 13227 13231 13236 13240 13243 13246 13247 13264 13274 13280 13292 13322 13373 13431 13438 13440 13456 13498 13514 13541 13543 13590 13612 13617 13696 13837 13845 13889 14336 14337 14338 14344 14345 14348 14349 14350 14356 14359 14360 14362 14364 14385 14387 14395 14405 14406 14407 14408 14410 14413 14415 14416 14418 14419 14422 14423 14424 14425 14426 14428 14429 14430 14432 14433 14434 14438 14439 14440 14445 14457 14458 14459 14462 14488 14490 14500 14523 14527 14545 14548 14549 14555 14593 14607 14610 14611 14614 14618 14619 14624 14629 14632 14633 14636 14638 14640 14642 18091 18779 19064 19065 19195 19232 19295 19336 19629 20022 20103 20142 20156 20275 21931 22126 22174 22209 22227 22233 22243 22268 22452 22873 22941 23031 23549 23630 23634 23639 23640 23643 23663 23674 23679 23768 23787 23846 23890 23912 23926 23947 23948 23981 24029 24070 24156 24167 24185 24277 24321 24322 24325 24332 24334 24356 24365 24378 24448 24450 24460 24461 24466 24497 24501 24506 24507 24515 24525 24554 27448 27654 28056 28072 28113 30061 30139 30189 30198 30298 30300 30309 30313 30315 30316 30317 30319 30320 30321 30323 30328 30330 30331 30357 30358 30359 30385 30400 30402 30403 30405 30407 30408 30409 30414 30415 30417 30419 30420 30421 30424 30426 30428 30429 30433 30443 30448 30450 30452 30453 30460 30462 30496 30504 30508 30511 30512 30523 30526 30529 30545 30558 30573 30581 30593 30599 30601 30602 30606 30607 30609 30610 30611 30613 30614 30615 30621 30623 30625 30628 30629 30630 30632 30637 30640 30642 30645 30647 30648 30649 30652 30654 30656 30659 30662 30663 30664 30665 30666 30671 30678 30688 30691 30692 30695 30698 30700 30702 30709 30717 30718 30719 31600 31751 31814 31837 31840 31842 31878 31958 32006 32008 32021 32022 32023 32025 32064 32067 32069 32073 32076 32077 32081 32082 32085 32087 32088 32089 32093 32099 32103 32106 32117 32118 32126 32189 32198 32213 32254 32513 32519 32562 32621 32661https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/89/189?format=asciiInfraredRadiodefaultJ/ApJS/89/189/table1DetectionsrecnoRecord number assigned by the VizieR team.
