Archive Access and Data Retrieval

Oasis can be used to retrieve astronomical data from a variety of sources, including the following:

• Image archives (e.g. IRAS, DSS, VLA)
• Catalog archives (e.g. IRSA, CDS, NED)
• Image metadata (e.g. coverage maps for 2MASS, ISO)
• One-Dimensional Data Collections
  (e.g. spectra, light curves, strip scans)[coming]

Every data request is handled through a separate processing thread, so other work can proceed in parallel. All retrieved data are stored locally and (when possible) are added to the current display either as the background (in the case of images), map overlays, or in other pop-up data windows. These files can be re-read from disk at a later date.
