cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomysurveysradio-continuum-emissionThe Planck Early Release Compact Source Catalogue (ERCSC) includes nine lists of highly reliable sources, individually extracted at each of the nine Planck frequency channels. To facilitate the study of the Planck sources, especially their spectral behaviour across the radio/infrared frequencies, we provide a 'bandmerged' catalogue of the ERCSC sources. This catalogue consists of 15191 entries, with 79 sources detected in all nine frequency channels of Planck and 6818 sources detected in only one channel. We describe the bandmerging algorithm, including the various steps used to disentangle sources in confused regions. The multifrequency matching allows us to develop spectral energy distributions of sources between 30 and 857GHz, in particular across the 100GHz band, where the energetically important CO J=1->0 line enters the Planck bandpass. We find ~3{sigma}-5{sigma} evidence for contribution to the 100GHz intensity from foreground CO along the line of sight to 147 sources with |b|>{30deg}. The median excess contribution is 4.5+/-0.9 per cent of their measured 100 GHz flux density which cannot be explained by calibration or beam uncertainties. This translates to 0.5+/-0.1K.km/s of CO which must be clumped on the scale of the Planck 100GHz beam, i.e. ~10-arcmin. If this is due to a population of low-mass (~15M_{sun}_) molecular gas clumps, the total mass in these clumps may be more than 2000 M_{sun}_. Further, high-spatial-resolution, ground-based observations of the high-latitude sky will help shed light on the origin of this diffuse, clumpy CO emission.2016MNRAS.458.3619Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/3619CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/88 : Planck Early Release Compact Source Catalogue (Planck, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/3619https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/3619http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/3619https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/3619https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/3619http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/3619GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/3619/table4 (List of sources with 100 GHz flux excess in the Planck ERCSC)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/3619/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/3619/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/3619/table4?GETtext/xml+votable180.050000true266.8208-28.38330.0055555555555555566/180 700 862 1231 1539 1546 1701 1781-1782 2414 2836 3052 3063 3067 3198 3303 3630 3648-3649 3681 3819 3886 4285 4695 5597 5767 6636 7446 7606 7623 7911 7969 9460 9633 10163 11594 11639 12619 12842 13049 13292 13927 13995 14029 14285 14293 14299 14304 14306-14307 14314 14317 14358-14359 14406 14409 14608 14621-14622 14624 14641 14667 14671 14682-14683 14691 14704 14716 14744 15067 15286 15368 15431 15452 15494 15634 15667 15681 15683 16027 16093 16281 16298 17414 18378 18624 19101 19190 20099 20725 20849 21121 21215 21439 21456 21458 21504 21510 21564 21641 21646 21758 21768 22208 22363 22396 22855 22873 22950 23099 23121 23637 23645 23764 23969 24185 24378 24845 25302 25501 25630 26131 26292 27060 27765 28083 28673 28830 28890 28912 28918 29072 29091 29101 29116 29213 29505 29508 29510 29522 29533 29675 30218-30219 30251 30262 30317-30318 30341 30363 30366 30420 30601 30624 30694 30715 30719 31451 31559 31894 31915 33094 33102 33115 33549 33684 33881 34104 34123 34264 34517 34572 34675 35440 36941 37190 37343 37371 37385 37474 37688 37752 37884 37886-37887 37895 37931 37937 38024 38416 38763 38916 38954 39250 39386 39542 40060 40885 41072 41335 41543 41675 41678 41706 41772 41777 41782 41812 41820 41824 42046 42170 42172 42174 42207 42215 42225 42230 42376 42391 42436 42439 42441 42444-42445 42447 42449 42455 42457 42498 42611 42970 42981 43017 43026 43262 44069 44170 44247 44908 46310 46373 46964 47106 47828 48023 48123 489654.638248699215607e-23 9.475279485540455e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/3619?format=asciiMillimeterRadiodefaultJ/MNRAS/458/3619/table4List of sources with 100 GHz flux excess in the Planck ERCSCrecnoRecord number assigned by the VizieR team.
