HSA 8.2 includes also the following changes:

  • Re-organization of the Observation Constraints panel with a new Object Type tab that allows queries by Science Area and Science Category
  • The Proposal tab includes now the possibility to query by Co-authors and by strings contained in the proposal abstract
  • Improvements in the ingestion, visualization and retrieval system of User Provided Data Products (UPDPs)
  • Improvement of the accuracy of geometrical searches by upgrading the database engine
  • Improvement of the Postcards visor

  • all or selected results can be saved as a VOTable or a CSV file
  • contextual help, as well as a complete new help manual
  • a Log Console to visualise queries and error messages
  • possibility to configure the GUI with different colors

 

The new HSA contains a migration towards state of the art technology, including re-use of existing open source software libraries and databases, better client - server transport protocol to overcome firewall issues, and higher code re-usability with other Science Archive projects at ESAC.

  • Improvements on the information provided in the User Interface (HUI) per observation: Three new fields have been added containing information on the Pipeline version used to process the observation, the level of processing reached by the Pipeline and the final quality control status of the observation (passed/failed) after all the quality control checks have been completed.
  • The HSA is already prepared to accept and distribute new level 2.5 products (produced by the combination of more than one AOR) that will be generated by the PACS and SPIRE pipelines in the near future.
  • Further major fixes adressing the interaction with the Data Processing system resulting in the overall improvement of the performance of the whole system (HSA + HIPE)

    • The tar file contains now a top directory named with the request ID to the HSA
    • Under this top directory the hierarchical structure of the data has not been changed.
    • However, the xml file needed to import the data into HIPE has been done visible and it is also now immediately under the new top directory
  • This new tar structure requires HIPE 4.0 or higher in order to import the tar file into HIPE
  • When using HIPE version 4.1 or higher, importing the HSA tar file into HIPE does not require uncompression.
  • String queries in the HSA User Interface are now case insensitive
  • Further major fixes for the interaction with the Data Processing system
