New Release of the Hubble Spectroscopic Legacy Archive (HSLA)
Since early 2016 (Cycle 24), the astronomical community has been offered a novel way of mining the Mikulski Archive for Space Telescopes (MAST) data from the UV spectrographs onboard HST through the Hubble Spectroscopic Legacy Archive (HSLA). The HSLA provides quick-look spectra for individual COS/FUV exposures, co-added COS/FUV spectra, and individual calibrated COS/NUV exposures publicly available in MAST. These data are packaged into "smart archives" according to target type and scientific themes to facilitate the construction of archival samples for common science uses.
We announce a new release of the HSLA. This release now contains COS/NUV co-added spectra along with all newly public COS/FUV and COS/NUV individual and co-added spectra added since April 2017. The COS/FUV co-added products now include LP3 and LP4 in addition to LP1 and LP2 with updated dispersion solutions. The COS/FUV blue modes (G130M/1055, 1096 and 1222) are also now included in the HSLA co-added COS/FUV spectra. Finally, this release captures the latest updates to the COS/FUV and COS/NUV reference files. In particular, this release of the HSLA was timed to inform proposers in preparation for the HST Cycle 26 call for proposals.
The HSLA products are available on MAST at: https://archive.stsci.edu/hst/spectral_legacy/ together with a description of their contents. Questions about the content of the HSLA can be sent to firstname.lastname@example.org.
