cds-question@unistra.frastrophysical-masersradio-astronomyradial-velocitystellar-distanceWe present a statistical analysis of 482 6.7GHz methanol maser sources from the available literature, on their maser emission and the characteristics of their associated infrared sources. On the color-color diagram, more than 70% of the objects fall within a very small region (0.57<=[25-12]<=1.30 and 1.30<=[60-12]<=2.50). This suggests that 6.7GHz methanol maser emission occurs only within a very short evolutionary phase during the earliest stage of star formation. The velocity ranges of the masers belong to two main groups: one from 1 to 10km/s, and one from about 11 to 20km/s. These velocity ranges indicate that the masers are probably associated with both disks and outflows. The correlations between the maser and infrared flux densities, and between the maser and infrared luminosities, suggest that far-infrared radiation is a possible pumping mechanism for the masers which most probably originate from some outer molecular envelopes or disks.2003ChJAA...3...49Xhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ChJAA/3.49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/110/81 : Methanol masers towards IRAS sources (van der Walt+ 1995)J/AZh/72/22 : A 95 GHz Survey of Methanol Masers (Valtts+, 1995)J/MNRAS/291/261 : Methanol maser of IRAS-selected sources (Walsh+ 1997)J/A+AS/134/115 : Medicina 6.7GHz methanol masers survey (Slysh+ 1999)J/A+AS/143/269 : 6.7GHz methanol maser emission survey (Szymczak+, 2000)J/A+A/403/1095 : 6.7GHz methanol masers survey of low-mass YSO (Minier+ 2003)J/A+A/410/597 : Warm dust near methanol masers (Walsh+, 2003)J/A+A/413/233 : 12.2 GHz methanol survey (Blaszkiewicz+, 2004)J/A+A/428/1019 : Rest frequencies of methanol maser lines (Mueller+, 2004)J/A+A/434/613 : Water maser survey of methanol masers (Szymczak+ 2005)J/MNRAS/359/1498 : Class I and class II methanol masers (Ellingsen+, 2005)J/A+A/432/737 : 6.7GHz Methanol Masers General Catalogue (Pestalozzi+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ChJAA/3.49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ChJAA/3.49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ChJAA/3.49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ChJAA/3.49https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ChJAA/3.49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ChJAA/3.49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/ChJAA/3.49/table1 (Parameters of CH3OH Spectra Source)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ChJAA/3.49/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ChJAA/3.49/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ChJAA/3.49/table1?GETtext/xml+votable180.050000true9.19795163.4839090.0055555555555555565/7207 7278 7377 7383 10556 10624 6/3011 3061 3303 3649 14063 14306 14309 14317 14353 14354 14355 14356 14453 14594 14604 14622 14630 14655 14671 14692 15390 15452 15671 15681 21458 21510 23764 23969 23982 24325 24365 24507 24509 24554 28714 28808 28809 28812 28817 28824 28825 28827 28874 28896 28900 28912 28913 28918 28919 29090 29091 29092 29094 29096 29097 29100 29101 29103 29116 29118 29119 29154 29160 29461 29504 29505 29507 29513 29529 30218 30219 30222 30241 30244 30245 30256 30258 30259 30262 30263 30268 30269 30312 30313 30315 30316 30318 30319 30328 30405 30416 30420 30421 30425 30595 30600 30601 30604 30616 30617 30618 30622 30644 30692 30694 30695 30701 30710 30716 30719 37244 37343 37839 37846 37850 37886 37893 37897 37900 37923 37924 37938 38020 38024 39251 39282 41597 41653 41655 41671 41676 41677 41678 41681 41683 41684 41685 41688 41696 41758 41759 41765 41766 41767 41770 41771 41772 41776 41777 41778 41780 41799 41804 41805 41812 41814 41815 41817 41820 41824 42159 42169 42170 42171 42172 42174 42207 42211 42214 42215 42217 42228 42229 42230 42378 42379 42382 42387 42390 42391 42393 42396 42397 42417 42436 42438 42441 42444 42445 42450 42451 42454 42455 42456 42457 42460 42461 42502 42515 43013 43015 43019 43021 43024 430414.439466485724119e-24 4.439466485724119e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ChJAA/3.49?format=asciiOpticalRadiodefaultJ/other/ChJAA/3.49/table1Parameters of CH3OH Spectra SourcerecnoRecord number assigned by the VizieR team.
