DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : This data set contains data that is used to assess the morphology, topography, and geologic context of each rover site, to determine surface photometric properties, and to constrain aerosol physical and radiative properties. The calibration has removed bias, dark current, and flatfield effects from the raw Navcam EDRs and resulted in the generation of estimated radiance-on-sensor data from Navcam, in units of W/m^2/nm/sr. No geometric or camera-model calibrations or transformations have been applied. For details, see Soderblom, J.M., J.F. Bell III, J.R. Johnson, J. Joseph, and M.J. Wolff (2008) Mars Exploration Rover Navigation Camera (Navcam) in-flight calibration, J. Geophys. Res., 113, E06S19, doi:10.1029/2007JE003003. Processing : MER Camera Payload RDRs are considered Level 3 (Calibrated Data equivalent to NASA Level 1-A), Level 4 (Resampled Data equivalent to NASA Level 1-B), or Level 5 (Derived Data equivalent to NASA Level 1-C, 2 or 3). The RDRs are reconstructed from Level 2 edited data, and are assembled into complete images that may include radiometric and/or geometric correction. MER Camera Payload EDRs and RDRs are generated by JPL's Multimission Image Processing Laboratory (MIPL) under the OPGS subsystem of the MER GDS. RDRs are also generated by the Athena Pancam Science and Microscopic Imager Science Teams under the SOAS subsystem of the GDS. RDR data products are generated by, but not limited to, MIPL using the Mars Suite of VICAR image processing software at JPL, the Athena Pancam Science Team using IDL software at Cornell University and JPL, and the Microscopic Imager Science Team using ISIS software at USGS (Flagstaff) and JPL. The RDRs produced are processed data. The input is one or more Camera EDR or RDR data products and the output is formatted according to the MER Camera EDR/RDR SIS. Additional meta-data may be added by the software to the PDS label. There may be multiple versions of MER Camera RDRs. Data : RDR products generated by MIPL have a VICAR label wrapped by a PDS label, and their structure can include the optional EOL label after the binary data. RDR products not generated by MIPL may contain only a PDS label. Or, RDR products conforming to a standard other than PDS, such as JPEG compressed or certain Terrain products, are acceptable without a PDS header during mission operations, but may not be archivable. The RDR data product is comprised of radiometrically decalibrated and/or camera model corrected and/or geometrically altered versions of the raw camera data, in both single and multi-frame (mosaic) form. Most RDR data products have PDS labels, or if generated by MIPL (OPGS), dual PDS/VICAR labels. Non-labeled RDRs include JPEG compressed products and the Terrain products. Software : MER Camera Payload downlink processing software is focused on rapid reduction, calibration, and visualization of images in order to make discoveries, to accurately and expeditiously characterize the geologic environment around the rover, and to provide timely input for operational decisions concerning rover navigation and Instrument Deployment Device (IDD) target selection. Key software tools have been developed at Cornell University, at JPL by the MIPL, SSV, and APSS groups, at NASA Ames, and at the USGS/Flagstaff. These tools can also be used to process MI images (see below), as well as Navcam and Hazcam images, which have substantial scientific potential in addition to their operational importance PDS-labeled images and tables can be viewed with the program NASAView, developed by the PDS and available for a variety of computer platforms from the PDS web site http://pdsproto.jpl.nasa.gov/Distribution/license.html. There is no charge for NASAView.

CONFIDENCE_LEVEL_NOTE See SODERBLOMETAL2008 for a description of Navcam in-flight calibration. The authors estimate that their absolute radiometric calibration has an absolute accuracy of 10% and a relative precision of 2.5%. The calibration pipeline includes steps to model and remove the bias offset, the dark current charge that accumulates in both the active and readout regions of the CCD, and the shutter smear. It also corrects pixel-to-pixel responsivity variations using flat-field images.

ABSTRACT_TEXT This data set contains radiometrically calibrated MER-1 Navcam data. The calibration has removed bias, dark current, and flatfield effects from the raw Navcam data, resulting in estimated radiance-on-sensor data in units of W/m^2/nm/sr. No geometric or camera-model calibrations or transformations have been applied.
