Each covers about 400 square kilometers of the lunar surface, and contains two co-registered images. Transmitted signal was right-circular polarization, images are therefore left-circular and right-circular. Images are projected as Mercator maps for latitudes less than 16 degrees, Lambert (small-angle cone) between 16 and 48 degrees, Lambert (large-angle cone) between 48 and 80 degrees, and polar stereographic between 80 and 90 degrees.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.hstk-l-rtls-4-3.8cm-v1.0_kvn5-zf8v", "issued": "2018-06-26", "keyword": ["moon", "pre-magellan"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=HSTK-L-RTLS-4-3.8CM-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": "HAYSTACK MOON RADIO TELESCOPE RESAMPLED 3.8 CM RADAR V1.0"}
