mast_search_v13Recent updates to the modernized MAST search form have added access to the new CLASSY HLSP collection, and number of new interface improvements.

Search CLASSY Data

  • In addition to Hubble mission data, users can now use the simple drop-down menu at the top of the page to switch over to searching within the CLASSY High-Level Science Product, with plans to integrate additional HLSPs in the future.  CLASSY (COS Legacy Archive Spectroscopic SurveY) is a treasury survey that constructs the first high-quality, high-resolution far-ultra violet spectral database of nearby star-forming galaxies using data from the Hubble Space Telescope archive.  Custom search parameters are available for specialized searches within this collection, including galactic stellar mass and star formation rate.

Product Download Enhancements

  • Download up to 2000 observations in a single batch (previously only 100 were supported) directly through the interface.
  • Generate an API script for downloads directly from the results page, which also has the advantage of no limit on the number of datasets.
  • Quickly select recommended products, allowing quick downloads of common product types.
  • View a summary of the products selected before downloading (using the overlay 'Files =' link).
  • Download exclusive-access data via the API using Auth.MAST Tokens.

We always welcome your feedback on our search interfaces, so please reach out through the Archive Help Desk with any comments or questions on these updates!
