cds-question@unistra.frmolecular-cloudsradio-spectroscopyWe present intensity-corrected Herschel maps at 100, 160, 250, 350, and 500{mu}m for 56 isolated low-mass clouds. We determine the zero-point corrections for Herschel Photodetector Array Camera and Spectrometer (PACS) and Spectral Photometric Imaging Receiver (SPIRE) maps from the Herschel Science Archive (HSA) using Planck data. Since these HSA maps are small, we cannot correct them using typical methods. Here we introduce a technique to measure the zero-point corrections for small Herschel maps. We use radial profiles to identify offsets between the observed HSA intensities and the expected intensities from Planck. Most clouds have reliable offset measurements with this technique. In addition, we find that roughly half of the clouds have underestimated HSA-SPIRE intensities in their outer envelopes relative to Planck, even though the HSA-SPIRE maps were previously zero-point corrected. Using our technique, we produce corrected Herschel intensity maps for all 56 clouds and determine their line-of-sight average dust temperatures and optical depths from modified blackbody fits. The clouds have typical temperatures of ~14-20K and optical depths of ~10^-5^-10^-3^. Across the whole sample, we find an anticorrelation between temperature and optical depth. We also find lower temperatures than what was measured in previous Herschel studies, which subtracted out a background level from their intensity maps to circumvent the zero-point correction. Accurate Herschel observations of clouds are key to obtaining accurate density and temperature profiles. To make such future analyses possible, intensity-corrected maps for all 56 clouds are publicly available in the electronic version.2018ApJ...852..102Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/852/102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/139 : Herschel Observation Log (Herschel Science Centre, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/852/102https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/852/102http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/852/102https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/852/102https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/852/102http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/852/102GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/852/102/table1 (Nearby Globules in the Herschel Archive)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/852/102/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/852/102/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/852/102/table1?GETtext/xml+votable180.050000true9.767552.8544440.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/ApJ/852/1026/1075 1290 1847 2948 2957 3331 15426 15630 15790 15816 15857 22814 23704 24300 24305 29211 29367 29551 29560 29597 29653 30228 30231 30344 30519 30623 32083 37676 37747 37816 37817 37819 37820 37955 38435 38438 39141 39163 39186 39327 39361 39396 41403 41606 41635 41639 41742 41748 41870 42472 42705 42777 43010https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/852/102?format=asciiRadiodefaultJ/ApJ/852/102/table1Nearby Globules in the Herschel ArchiveSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
