cds-question@unistra.frmolecular-cloudsextinctionIn this paper, we derive an improved core mass function (CMF) for the Pipe Nebula from a detailed comparison between measurements of visual extinction and molecular-line emission. We have compiled a refined sample of 201 dense cores toward the Pipe Nebula using a two-dimensional threshold identification algorithm informed by recent simulations of dense core populations. Measurements of radial velocities using complimentary C^18^O(1-0) observations enable us to cull out from this sample those 43 extinction peaks that are either not associated with dense gas or are not physically associated with the Pipe Nebula. Moreover, we use the derived C^18^O central velocities to differentiate between single cores with internal structure and blends of two or more physically distinct cores, superposed along the same line of sight. We then are able to produce a more robust dense core sample for future follow-up studies and a more reliable CMF than was possible previously.2009ApJ...699..742Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/699/742CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/462/L17 : Dense cores in interstellar molecular clouds (Alves+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/699/742https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/699/742http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/699/742https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/699/742https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/699/742http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/699/742GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/699/742/table2 (Core properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/699/742/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/699/742/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/699/742/table2?GETtext/xml+votable180.050000true257.6703-28.39980.0055555555555555566/28839 28841 28859 28862 28863 28906 29186 29187 29189 29190 29191 29193 29200 29201 29203 29204 29206 29209 29210 29211 29212 29214 29215 29237https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/699/742?format=asciiOpticaldefaultJ/ApJ/699/742/table2Core propertiesrecnoRecord number assigned by the VizieR team.
