What is the HLA?

The Space Telescope Science Institute (STScI), the Canadian Astronomy Data Centre (CADC) and the ST-ECF are working together to optimize the future scientific return from the Hubble archives by producing enhanced data products and efficient data discovery and access services - collectively known as the Hubble Legacy Archive (HLA) - with the goal of capturing expertise in Hubble and assuring the maximum utility of Hubble data for long-term use by the community. The HLA provides footprints ACS, WFPC2, STIS, NICMOS, FOS, and GHRS, enhanced image products for ACS and WFPC2, and NICMOS grism spectra.

The Data Release 1

The ST-ECF is pleased to announce the availability of the first data release of 2470 individually validated NICMOS extracted grism (G141) spectra as part of Data Release 1 (DR1) of the HLA . Spectra from about 80% of all in-focus NICMOS G141 pointings up to July 2007 are available. One of the 2470 spectra in DR1. Data are distributed as FITS files, and a preview as shown here is available for each extracted target.

Users of HLA data sets are requested to include the following acknowledgment in any resulting publications:
"Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA)."
