Current Object Catalog Column Descriptions

The Current Catalog (currentcat) gives information on the current status of each object, including the most recent orbital data for those objects still in orbit. All the info in currentcat is implicit in, and derived from, the main catalogs. Its role is to provide an easy summary of the satellite catalog for those not interested in the most detailed nuances.
