C-BIDRs have been generated by computing 3x3 pixel arithmetic moving averages from the F-BIDRs. Each C1-MIDR is in a sinusoidal equal area projection and has an origin at 0 degrees latitude, with the central meridian defined as the longitude bisecting the mosaic. Each C1-MIDR has 7K lines (aligned with latitudes) and 8K samples, arranged as 56 1K x 1K files on the CD-ROMs. C1-MIDRs, with their 225m pixel widths, are designed to cover the planet at reasonably high resolution and high signal to noise ratio. The 1K x 1K files have a VICAR2 format, with embedded VICAR2 labels. The data have been placed on CD-ROMs with documentation, detached Planetary Data System labels, and summary tabular information. Over the course of the first mapping cycle, 190 C1-MIDRs have been generated, for a total volume of 10.6 Gbytes. Note: C1-MIDRs also exist as photoproducts that have had a linear contrast enhancement applied. Photoproducts are generated from 7K x 8K assemblage of files, so there is one photoproduct per C1-MIDR. Finally, in some cases a cross track seam removal process has been applied. See the CONTENTS.TAB file on the relevant MIDR CD-ROM volume for information on which MIDRs have been seam-corrected. Please refer to the F-BIDR (MGN-V-RDRS-5-BIDR-FULL-RES-V1.0) data set description for more details on radiometric and geometric processing of Magellan SAR data."
