A. 2023 S- and X-band frequency and amplitude data from the Voyager 1 Jupiter egress radio occultation, recovered from NSSDCA Merged Occultation Data. There is almost no documentation accompanying the file in NSSDCA. 2023-02-20 1.0 Initial version of data recovered from NSSDCA and converted to a pair of PDS4 tables. The data have been reformatted into physical records that are commensurate with the original logical records. Records are delimited by carriage-return line-feed pairs. A new PDS4 label has been generated. 1979-03-05T18:07:21.285Z 1979-03-05T18:41:55.000Z Calibration Derived S- and X-band radio frequency and amplitude data for the Voyager 1 Jupiter egress radio occultation. =Voyager Mission urn:nasa:pds:context:investigation:mission.voyager data_to_investigation Deep Space Network Host Description of the DSN as an observatory. urn:nasa:pds:context:facility:observatory.dsn is_facility DSS 63 Telescope Description of the DSS 63 antenna. urn:nasa:pds:context:telescope:madrid.dss63_64m is_telescope DSN Radio Science Instrumentation Instrument Description of the DSN radio science instrumentation urn:nasa:pds:context:instrument:dsn.rss is_instrument Voyager 1 Spacecraft Host Description of the Voyager 1 spacecraft. urn:nasa:pds:context:instrument_host:spacecraft.vg1 is_instrument_host Voyager 1 Radio Science Instrumentation Instrument Description of the radio science instrumentation aboard Voyager 1. urn:nasa:pds:context:instrument:vg1.rss is_instrument Jupiter Planet urn:nasa:pds:context:target:planet.jupiter data_to_target PSPA-00347:dr005500_f00004.phys.1 data_to_derived_source_product NSSDCA The value of external_source_product_identifier is constructed from the NSSDCA identifier, an ASCII colon, and the file name. vg1_radio_egr.tab 2021-09-08T09:59:00 290444 1b81f907bb23fd5a9dc3ca6daf8ddfcc This file was copied from the external source product with minor reformatting to create two Table_Character data objects. The first contains one identifying header record; the second contains many data records. Each record is delimited by a Carriage-Return Line-Feed pair. 0 1 This Table has one header record with twelve fixed-width fields followed by one Carriage-Return Line-Feed record delimiter.
