Rings Node Migration Plan

Mark & MitchPDSMC, UCLA

November 28-29, 2012

PDS4 Migration Overview

• In addition to several rings specific PDS3 data sets, we maintain a number of secondary data sets including:• Atmospheres• Cassini CIRS and Cassini UVIS

• Imaging• Cassini ISS and Cassini VIMS• Voyager ISS

• SBN• New Horizons Jupiter - LORRI

• We plan to take the lead in the data migration for Cassini CIRS & Voyager ISS.

• FY13 & FY14• Derived Astrometric Data• Derived Ring Radial Profiles – three Cassini instruments• Cassini CIRS • Voyager ISS• Derived Ring Radial Profiles – six ground based data sets

PDS4 Migration Overview (3)

Migration Plan FY13/FY14

• Astrometry• ASTROM_0101 – April 2013 (build 3b).• This is the data set we've been using for prototyping.• Currently updating the prototype for build 3a.

• ASTROM_0001 – Low hanging fruit• Similar to ASTROM_0101 so software will support with

minimum modification.• Plan to add this PDS3 data set as a new collection to the

bundle we developed for ASTROM_0101.

Migration Plan FY13/FY14 (2)

• Cassini derived ring occultation profiles• UVIS, VIMS and RSS teams have generated ~ 200 ring

profiles using similar formats.• All were designed with PDS4 in mind.• Migration will require developing Rings Node Data

Dictionary.• Peer review with PDS3 & PDS4 labels and organization.• Start in FY13; finish in FY14.

Migration Plan FY13/FY14 (3)

• Cassini CIRS• Reformatting pipeline extension (1)• The team delivers volumes in the “Vanilla” variable

length record format. – Detectors, targets, modes are all mixed together.

• Our pipeline breaks apart data files by detector & observation using fixed-length records.• All efforts were tabled last year when the version 3.1

delivery broke our pipeline.• Version 3.2 will be stable ~ January 2013 – we hope.

Migration Plan FY13/FY14 (3)

• Cassini CIRS (2)

FY13 plan: • Update the PDS3 reformatting pipeline and begin

producing reformatted PDS3 volumes.• Begin PDS4 migration pipeline development.• Automated PDS4 migration pipeline in place in FY14.

Migration Plan FY14/FY15 (1)

• Voyager ISS processed data sets• Original PDS3 data in one, 38 volume, data set. • New data in four data sets (Jupiter, Saturn, Uranus,

Neptune).• Uncompressed raw, calibrated, and geometrically

corrected images.• Will begin migration development in FY14; finish in FY15.

Migration Plan FY14/FY15 (1)

• 28 Sgr Occultations of Saturn's rings• Six data sets of ground based observations.• Combine aspects of the astrometry and occultation data

sets previously migrated.• Will begin and finish in FY14.
