Scanning Machines

• Gamma I being used to scan 2 plates per day
• Gamma II still suffering from unknown problems

Currently Scanning

• IS plates
• 86 complete
• XO plates
• being scanned between shipments of IS plates
• 38 complete

GSC-II Plate Processing Status

• IS, XI, and some XO plates currently being
  processed
• IS survey is 44 complete
• XI survey is 34 complete
• XO survey is 2 complete
• going slower due to loss of Fabrizia!

7
GSC-II Plate Processing Status

• No global recalibrations have been performed
  recently
• A few plates have needed updating
• All processed data now has the latest astrometry
  and photometry applied
• IV N (IS and XI) plates have not been loaded into
  the COMPASS database
• This processed data has been written to tape and
  will be loaded at a later date

Currently Compressing

• XI Survey
• 83 complete
• XO Survey
• 10 complete
• IS Survey
• 78 complete

10
Status of DSS Data Migration

• All DSS-I, DQVS, and DSS-II data to be moved to a
  raid array
• will eventually serve a web page interface
• All of DSS-I and DQVS migrated
• Problems in migrating data
• migration of DSS-II has been put on hold while
  technical issues are sorted out

11
Currently Available DSS Data

• Data being served to web page via a CD jukebox
• jukebox and web page maintained by Archive Branch
• DSS-I, DQVS, and only part of DSS-II currently
  available online
• All headers completed, but not currently
  available online

12
Future Activities

• Complete scanning, processing, and compression of
  XI, XO, and IS surveys
• Limited by telescope availability to complete
  observations
• Completion of DSS data migration and header
  availability
• Load all processed data onto COMPASS
• Perform any recalibration tasks to all data on
  the database side
• Operational goals may need to be scaled back due
  to staffing and resource issues
