Beyond the scientific value of the observation, this has been so far the first and unique occasion during the cruise phase to verify the execution of the science observing sequences as they will be operated at Jupiter. The imager has been able to capture the Moon region straddling the terminator in L and M astronomic bands. Some surface features are recognizable and have been mapped with the support of the geometric information available for JIRAM data. Spectral pixels acquired in parallel with the M image have been used to retrieve temperature and spectral emissivity of the sounded region. Data Coverage and Quality ========================= During the Juno's Earth fly-by, on October 9, 2013, instruments were switched ON the for their status and responsivities checking. While the S/C was moving towards the Earth, JIRAM was active, targeting the Moon, since 13:05 up to 13:50 UTC about. Throughout this time period the spacecraft moved along its counterclockwise Sun orbit passing between Earth (on the left) and Moon (on the right). In the pass geometrical configuration, the Sun was approximately in the opposite direction of the spacecraft motion versus and the Moon, at the Juno's closest approach, was divided in two halves by the terminator. In this configuration JIRAM's telescope swept the body that appeared as entering in the image plane from the left and crossing it towards the right side. 132 images both for science and calibrations both in L and M bands with an equivalent amount of spectral measurements have been produced in this 45-minutes acquisition. Among those targeting the Earth's satellite, some of them have been chosen for a preliminary analysis. There is not any particular reason in the choice as in the short period of observations the sounded region at the terminator practically did not experience variations. Data Coverage and Quality ========================= All data in the stated interval are included, to the best of our knowledge and attempts to determine completeness.

DATA_SET_TERSE_DESC = "This data set contains the CODMAC Level 2 JIRAM data for the JUNO mission" DATA_SET_DESC = " Data Set Overview ================= JIRAM Level 1b data products consist of the data produced by the instrument reconstructed from the scientific telemetry, sorted by instrument state and data type, and provided with spacecraft position, velocity and attitude information. Any other spacecraft telemetry relevant for calibration and processing (e.g. temperature of the receiver) is also be included. JIRAM data consist of two parts: the first contains ancillary data produced by instrument and used to interpret scientific data, the second is science data. The scientific products are spectra or images that are downloaded form the S/C in data packets or sub-frames. Packets are then recombined by IOT in image or a number of spectra as function of the used submode. Data organized in submodes are not compressed. Compression on the data is possible to reduce the data volume. Lossy compression is possible on imager data; the images can be reduced to JPEG format. The lossy compression reduces the images data volume of a factor 6. Lossless compression can be applied to spectra. The lossless compression would produce a compression of a variable factor that depends on the datum itself. The factor is about 1.5 on average. For each Data Set JIRAM team will deliver a spreadsheet containing auxiliary information. In each spreadsheet all products are ordered by acquisition time. This file will give an overview on the data set acquisition. Data ==== The 'JUNO MOON JIRAM EXPERIMENT DATA RECORD V1.0' Data Set contains scientific telemetry generated by the instrument, edited to remove duplications, zero-padded for missing packets, and correlated with geometric information needed to locate observations in space and time. No other kind of processing is applied to the data. Coordinate System ================= Locations on the surface of JIRAM are expressed in planetocentric coordinates. Longitude is comprised in the range 0 - 360 degrees. Data Quality ============ Data quality in a data product label is indicated through the DATA_QUALITY_ID element, and measures the integrity of the telemetry stream from the instrument. The permitted values of DATA_QUALITY_ID are the following: 1: complete data 0: incomplete data " END_OBJECT = DATA_SET_INFORMATION OBJECT = DATA_SET_MISSION MISSION_NAME = "JUNO" END_OBJECT = DATA_SET_MISSION OBJECT = DATA_SET_REFERENCE_INFORMATION REFERENCE_KEY_ID = "N/A" END_OBJECT = DATA_SET_REFERENCE_INFORMATION OBJECT = DATA_SET_TARGET TARGET_NAME = MOON END_OBJECT = DATA_SET_TARGET OBJECT = DATA_SET_HOST INSTRUMENT_HOST_ID = "JNO" INSTRUMENT_ID = "JIR" END_OBJECT = DATA_SET_HOST END_OBJECT = DATA_SET END
