Two new HLSPs were released; M87-HST-UV is the deepest ultraviolet image of M87 while TESS-YSO offers TESS light curves for young stellar objects. We also had an update to an outer planet imaging program and updates to our TESS-based HLSPs.
Announcing the (re-)release of the Hubble Spectroscopic Legacy Archive! This latest version provides coadded COS and STIS spectra, includes classifications for each target, and supercedes the previous version of HSLA.
BOSZ 2024 stellar models updated to fix two issues; users are encouraged to re-download models to get these fixes. Updates were also made to the TESS-based TICA and QLP products.
The SDSS Legacy Archive at MAST (SLAM) now includes the SDSS Legacy Spectra Survey, the SDSS Supernova Survey, and the SDSS Extension for Galactic Understanding and Evolution (SEGUE). This dataset provides optical-wavelength 1-D spectra for over 1.8 million stars, galaxies, and quasars.
We recently added the ability to see JWST image previews in our modernized search form. Coming soon to other MAST missions! Plus, a bonus: a dark/light mode toggle 🌙 ☀️
High-Level Science Products at MAST added a new collection of spectroscopic observations from the Apache Point Observatory including targets from the legacy Mount Wilson survey. Updates were also made to the usual TESS-based collections, as well as new Neptune observations in the OPAL collection.
🧠 💪 This month, the SMARTS data release 2 was published, adding a million simulated light curves of the Kepler bonus background data. Mega-MUSCLES was also updated with SEDs for an additional 12 M dwarf stars. We also made updates to our usual group of TESS-based HLSPs.
A change to the TESS processing pipeline resulted in a loss of photometric precision and transit search sensitivity. Corrected data are now available in MAST.
The SDSS Legacy Archive at MAST (SLAM) now includes images and photometry from the SDSS Legacy Imaging Survey. This dataset provides wide-field images and ugriz photometry for 14,055 square degrees of the sky.
The evil Dr. Nefarious has, for the time being, been defeated. Thank you to everyone who attended our AAS workshop!
Spitzer results are no longer returned for coordinate-based searches, nor for exo-mast. For these types of searches, please query IRSA directly.
A new High-Level Science Product provides imaging survey data of five different lensing galaxy clusters using data from both JWST and HST, and updates were made to the usual TESS-based collections.
MAST users should be aware that older Table Access Protocol (TAP) services will be turned off on June 26. Updated services are available to replace all previous functionality, but users may need to make changes to scripts using the previous services. More details are available to help users make this transition and we're happy to answer further questions!
Updates to existing High-Level Science Products at MAST included new data for the QLP, REFERENCE-ATLASES, TESS-SPOC, and TICA collections.
