Three channels (so- called blue, green and red) were devoted to the observation of the scattering of solar light by cometary dust grains, in emission-free countinuum bands. Four other channels (so called OH, CN, CO+, C2) were devoted to the observation of light emitted by cometary gases.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.gio-c-ope-3-rdr-halley-v1.0_ha2c-6fq8", "issued": "2018-06-26", "keyword": ["giotto", "halley"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=GIO-C-OPE-3-RDR-HALLEY-V1.0", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "GIOTTO OPTICAL PROBE PHASE MEASUREMENTS V1.0"}
