SPT Data Releases

"The SPT is a 10-meter diameter microwave / millimeter / sub-millimeter telescope located at the NSF Amundsen-Scott South Pole Station, which is the best currently operational site on Earth for millimeter-wave survey observations, owing to the stable, dry atmosphere above the High Antarctic Plateau. NOTE: Data releases from specific analyses (e.g., bandpowers and covariances from power spectrum analyses, catalogs from galaxy cluster and point-source analyses) are linked along with the publications for those analyses below. These data are all also hosted at NASA's Legacy Archive for Microwave Background Data (LAMBDA) website."

Data Management "Plan for Archiving Data The archiving of SPT-SZ, SPTpol, and SPT-3G data takes place on two levels. The raw data, which is not of particular utility to the broader scientific community, are maintained in three locations. Two copies of the data exist on hard drives accessible to the SPT collaboration for analysis: one in Chicago and one at the South Pole. A third copy of the full data is maintained on tape at the National Energy Research Scientific Computing (NERSC) Center. For SPT-3G, a fourth copy will exist on disk at ANL. The data products of more interest to the community, namely the sky maps and associated data products, will be archived primarily on the LAMBDA server. A second copy of all of these products will be maintained, at least for the duration of the current SPT project, on the public SPT website. Plan for Making Data Used in Publications Available When a particular analysis is submitted to a scientific journal and posted on the arXiv preprint server, any data products that result from that analysis are immediately made available on the SPT public website (http://pole.uchicago.edu) and are soon uploaded to the LAMBDA server (http://lambda.gsfc.nasa.gov). Examples of this are catalogs of galaxy clusters and emissive sources, measurements of the amplitude of the CMB power spectrum, and cosmological parameter constraints. Responsiveness to SC Statement on Digital Data Management This data management plan fully follows SC Statement on Digital Data Management."
Data Policy "Data policy is set by consensus of the collaboration, which includes university and lab partners. The collaboration – in particular the P.I. and data managers at the University of Chicago – bear the responsibility for making data public. Public data products are hosted on University of Chicago machines and on the NASA Legacy Archive for Microwave Background Data Analysis (LAMBDA) server. Data Products and Releases Raw data from the SPT-SZ, SPTpol, and SPT-3G cameras are transferred from the South Pole to the main SPT computers in Chicago, converted to intermediate data files if necessary, and released to the collaboration, all on a daily basis. These time-ordered data are the primary input to the main analysis pipelines. Single-observation and coadded maps are custom-produced for specific science applications and are distributed to the collaboration as soon as they are available. Auxiliary data products (beams, bandpasses, etc.) are generated as needed (generally once per observing season) and are immediately available to the collaboration Public releases occur in concordance with the publication of major science results, and the products are posted on a website with instructions. Plan for Serving Data to the Collaboration and Community The SPT collaboration is committed to making data accessible to the wider community in as useful a format as possible. When a particular analysis is submitted to a scientific journal and posted on the arXiv preprint server, any data products that result from that analysis are immediately made available on the SPT public website (http://pole.uchicago.edu) and are soon uploaded to the LAMBDA server (http://lambda.gsfc.nasa.gov). Examples of this are catalogs of galaxy clusters and emissive sources, measurements of the amplitude of the CMB power spectrum, and cosmological parameter constraints. Moreover, the SPT team has released maps of the SPT-SZ data, and is committed to releasing maps from the SPTpol and SPT-3G. Sharing of pre-release data will be arranged through memoranda of understanding among all parties. Plan for Archiving Data The archiving of SPT-SZ, SPTpol, and SPT-3G data takes place on two levels.
