VEX-V-VMC-3-RDR-EXT3

DATE SET OVERVIEW This data set consists of image data taken by the Venus Monitoring Camera aboard Venus Express obtained during second extended mission starting with orbit 1110 until the current delivery. These image data are calibrated data and the image artifacts are removed as best as possible. PROCESSING The image data werde decompressed after download, labeled according to the label definition. The data were also radiometrically calibrated (dark current correction, flat field correction, stray light correction, blemish removal). An additional flat field correction based on inflight calibration data calculated for almost every orbit was also applied to remove the image artifacts. DATA There is only one data type associated with this dataset, radiometrically calibrated images. FILENAMING FOR IMAGE DATA The following structure of filenames was used VOOOO_MMMM_DDL.IMG camera id V orbit number OOOO image number in one orbit MMMM detector id DD (can be UV,VI,I1,I2) level (2) L examples: V1234_0023_VI1.IMG V1234_0323_UV2.IMG ANCILLARY DATA The ancillary data required to apply geometric correction to this data set are the VEXNAIF kernels, supplied by the Venus Express project under ftp://ssols01.esac.esa.int/pub//data/SPICE/VEX/kernels/ SPECIAL VALUES The following values are used for N/A and UNK in the image labels (as described in chapter 17 of the PDS standards reference): Signed Integer Real (4 byte) N/A 2147483648 1.E32 UNK 2147483647 1.E332 FOOTPRINT_POINT_LATITUDE and FOOTPRINT_POINT_LONGITUDE These two keywords together describe as a polygon the location of the image footprint on the Venus surface. Positive longitude direction is EAST. The footprint was calculated at many points (> 1,000), the 100 points with the smallest angle of the polygon were selected for the image label. The last and the first latitude/longitude pair are the same to guaranty a closed polygon. REVIEW This archival data set was truncat [truncated!, Please see actual data for full text]
