** THIS PAGE STILL BE UPDATED FOR APRIL 23 TELECON ... CHECK BACK LATER FOR THAT VERSION** UPDATES IN BLUE
Definitions:
Data Level | Brief Description | Nominal Delivery Schedule | ||
|---|---|---|---|---|
Raw | Raw telemetry data as received at the ground receiving station |
| ||
L0 | Binary CCSDS packets (as produced by the corresponding instrument; unpacked metadata | Within 30 minutes of telemetry arriving at the SOC. | ||
L1A | Extracted telemetry items; no calibrations or corrections applied; B and Vsc to all investigations | 1. L1A based on Survey data for SITL support: within 60 minutes of telemetry arriving at the SOC. 2. For burst data, within 24 hours of the downlink (and arrival at the SOC) of each complete burst segment. | ||
L1B | Extracted telemetry data to which instrument-level provisional calibrations have been applied; simple moments, spectral indices | 1. L1B based on Survey data for SITL support: within 60 minutes of telemetry arriving at the SOC. 2. For burst data, within 24 hours of the downlink (and arrival at the SOC) of each complete burst segment. | ||
Quicklook | Scientific data products that are generated using simplified science processing algorithms, e.g. with provisional calibrations. | 1. QL based on Survey data for SITL support: within 60 minutes of telemetry arriving at the SOC. 2. If there's a Burst-based QL, that will be available within 24 hours of the downlink (and arrival at the SOC) of each complete burst segment. | ||
L2A | "Instrument-level" research-grade scientific data product, best calibrations to shorter-term delivery date |
| ||
L2B | "Instrument-level" research-grade scientific data products, definitive products | available to the general research community within 35 days of telemetry downlink | ||
