cds-question@unistra.frsurveysapparent-magnitudeThe NASA Orbital Debris Observatory (NODO) astronomical survey uses a transit 3m liquid mirror telescope to observe a strip of sky in 20 narrowband filters. In this article, we analyze a subset of data from the 1996 observing season. The catalog consists of 18,000 objects with 10<V<19 observed in 10 narrowband filters ranging from 500 to 950nm. We first demonstrate the reliability of the data by fitting the Bahcall-Soneira model of the Galaxy to the NODO magnitude counts and color counts at various Galactic latitudes. We then perform a hierarchical clustering analysis on the sample to extract 206 objects, out of a total of 18,000, showing peculiar spectral energy distributions. It is a measure of the reliability of the instrument that we extract so few peculiar objects. Although the data and results, per se, may not seem otherwise particularly remarkable, this work constitutes a milestone in optical astronomy, since this is the first article that demonstrates astronomical research with a radically new type of mirror.1998ApJ...509..309Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/509/309CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/88 : Stellar Spectrophotometric Atlas (Gunn+ 1983)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/509/309https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/509/309http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/509/309https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/509/309https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/509/309http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/509/309GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/509/309/table3 (Peculiar objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/509/309/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/509/309/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/509/309/table3?GETtext/xml+votable180.050000true250.85881533.02059610.0055555555555555566/9077 9078 9079 9081 9082 9084 9141 9142 9157 9158 9159 9161 9162 9184 9333 9334 9337 9338 9340 9397 9398 9399 9401 9402 9403 9404 9413 9415 9417 9419 9477 9478 9479 9481 9482 9483 9488 9504 9733 9734 9735 9737 9738 9740 9744 9760 10357 10358 10361 10362 10363 10364 10421 10423 10425 10437 10438 10443 10501 10505 10507 10508 10757 10758 10761 10762 10763 28533 32633 32634 32635 32694 32697 32698 32700 32713 32714 32716https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/509/309?format=asciiOpticaldefaultJ/ApJ/509/309/table3Peculiar objectsrecnoRecord number assigned by the VizieR team.
