SAGE-Spec Data Deliveries

What is available?

SAGE-Spec delivers IRS spectra and MIPS observations of point and extended sources.

Please note that when a Legacy team delivers enhanced data products to IRSA, the data must go through a quality assurance (QA) and ingestion process before being available through IRSA search engines, and this process does not happen instantaneously. Direct data access to a more recent delivery may contain errors that will be caught by the QA process; an IRSA search of an older delivery permits access to data that have passed the QA process.

Note: The MIPS-SED spectra in DR2 (20100301) were revised on 2010-07-01. Users who downloaded the previous version of the data may have incorrect spectra for sources beginning with 85.1799-70.1862 or 85.2053-70.1704.

Getting the original Spitzer data

All of the original Spitzer data for Legacy programs are released to the community as soon as they complete end-of-campaign reprocessing (there is no proprietary period). For general information about how to access our, archive (and what to do with the data when you get in), please see Data Archive and Data Analysis & Tools.

To access data specifically from SAGE-Spec, you can retrieve data for program id (PID) 40159.
