Saturn Observation Guide README: This collection of files contains information on all of the Cassini science observation requests that focused on Saturn atmospheric science. The majority of this data was exported from the Cassini Information Management System (CIMS). The collection is comprised of 8 files (tables), one for each top-level category on the Saturn PDS Help Page, and the observation key. PDS Categories: Atm Properties - Only those requests that contributed to the study of atmospheric properties. Interior - Only those requests that contributed to the study of Saturn's interior. Dynamics - Only those requests that contributed to the study of atmospheric dynamics. Origin - Only those requests that contributed to the study of Saturn's origin. Aurora - Only those requests that contributed to the study of Saturn's aurorae. Mag_Ionosphere - Only those requests that contributed to the study of Saturn's magnetosphere and ionosphere as related to atmospheric science. Full - This is the full table with all requests. The above tables contain the following columns of data: Request - Request name ___ Team - The science team that owned the request. Target - The primary science target. Star (Occultations) - Name of targeted star for stellar occultations. Observation Type Code - Team defined code that identified the type of observation. Start Time (SCET)- Start time in spacecraft event time. Epoch - Epoch start time if it was a relative-timed request. Duration - Duration of request. End Time (SCET) - End time in spacecraft event time. +/- 24 hr of Periapse? - Yes/No, was this request within the period which started 1 day before periapse and ended 1 day following? Science Type - PDS help page listed science categories applicable (could be multiple). TWT/OST Segment - Identifies which discipline-led science integration team was responsible for including the request in the timeline and the segment in which it occurred. Rate (bps) - Data rate in bits per second. Data Volume Requested (Mbit) - The data volume, in megabits, requested by the science team during sequencing. TDS Data Downlinked (Mbit)* - The data, in megabits, that was received on the ground by the Telemetry Data System, recorded during the request's time period by the primary instrument. *Note on TDS Data: Data may be more than what was requested because of the following reasons, when they occurred. 1) There were multiple requests by the same team overlapping in time. 2) Data volume was policed for entire observation period (not by observation). It was common practice for instrument teams to shuffle data volume amongst their requests in the same period with a net zero impact to the data policing architecture. When this was done, a request may be commanded to record more/less than what was book kept in CIMS. SPASS Type - Indicates if a request had primary pointing control, or rode along with another instrument's pointing design. APGEN Type - Identified different types of requests within a team. Primary Pointing - Primary target orientation. Secondary Pointing - Secondary orientation, often to avoid flight rule violations, align boresights with target as desired, or to the advantage of ride-alongs. Pointing Agreement - If there was a special agreement between science teams, it would be recorded here. Key - The "Key" document provides a mapping of all the request name code that were used to a high level science description and other data, as indicated below. Request Name Code - Code, contained in the CIMS request name, that identified the type of observation. Target Body - The target of the observation (stellar occs may use Saturn or Star). Description - High level science description. Science Type Matrix: "x" indicates inclusion Origin Interior Atm. Properties Dynamics Aurorae Mag/Ionosphere Primary Team - Team driving the spacecraft pointing. Possible Ride-along Teams - Possible instrument teams that may have recorded complimentary data sets. Primary Pointing - Typical primary pointing. Secondary Pointing - Typical secondary orientation.
