cds-question@unistra.frinterstellar-mediumradio-astronomymolecular-cloudsLow-noise, 0.8MHz resolution spectra around 90GHz towards four hot core sources: Orion KL, W51 e1/e2, S140, and W3(OH), are presented. The observations were performed using the 3mm SIS receiver at the Onsala 20m telescope. The observations were made in the beam-switching mode, the spectrum intensity is given in T_A_^*^ and high-order polynomial baselines have been subtracted. At 90GHz the Onsala 20m telescope has a beam FWHM of ~42arcsec and a main-beam efficiency of ~0.6. Due to changes in frequency setting during the observing period the frequency ranges are not identical for each source, but in all cases the ranges include the transitions used to determine the upper column densities of amino acetonitrile (H_2_NCH_2_CN), vinyl acetylene (C_2_H_3_CCH), oxiranecarbonitrile (c-C_3_H_3_NO), and amino-ethanol (NH_2_CH_2_CH_2_OH), presented in the paper. Note that the absorptions, seen in the S140 and the W3(OH) spectra around the strong HCN-line at 90.663GHz, are artificial.2007A&A...473..177Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/473/177CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/473/177https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/473/177http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/473/177https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/473/177https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/473/177http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/473/177GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/473/177/list (List of objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/473/177/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/473/177/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/473/177/list?GETtext/xml+votable180.050000true83.810417-5.3750.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/473/1776/3649 15667 21439 30694https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/473/177?format=asciiRadiodefaultJ/A+A/473/177/listList of objectsNameNamemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
