篮球竞猜盈利|湖南体育职业The Archived Synthetic Data Iniative (ASDI) is an effort to enhance science with MAST data. The goal is to enable discoverability of synthetic observations of astronomical objects, and to enable users to analyze these products alongside real data.
Accelerating computing offers powerful new tools for studying the universe, especially when simulations and synthetic observations can be compared with real data. Over the past few years, MAST has collaborated on research and development activities to enhance simulated datasets, called the Archived Synthetic Data Initiative (ASDI). The primary goal of ASDI is to unite community-contributed simulations and synthetic data with MAST data to enhance the ability of any users to ask and answer hard astrophysical questions. The basic concept is that an ASDI contribution begins as a MAST HLSP. Two additional requirements are 1) to provide a custom search service for different synthetic data types, and 2) to provide a data simulation service suited to specific mission observing modes
篮球竞猜盈利|湖南体育职业In 2019, MAST began work developing a prototype ASDI web service. To demonstrate the ASDI concept, we have used an HLSP contribution of simulated galaxy halo gas spectra, and enabled simple STIS spectroscopic data simulations. In the first phase, we ingested the HLSP files and metadata, which we have exposed via a VO TAP service to enable searching for subsets of data products. In the second phase, MAST has developed a web service to take the pristine sky synthetic data products, modify them with basic data simulation steps on the server-side, and then return the final products to the user.
Contribute Synthetic Data
We welcome new contributions from the community to expand our holdings of these models and simulations. We will work with contributors to properly format their synthetic data files and begin the process of ingesting them as a new ASDI Project. An early conclusion of ASDI development was that a logical input to a MAST synthetic data service is the “pristine synthetic sky”, in its simplest form flux as a function of wavelength and/or position. This serves as the end point of astrophysical simulation steps, and the input to telescope or instrument simulation steps.
Our vision is that MAST synthetic data projects begin as MAST High-Level Science Products篮球竞猜盈利|湖南体育职业, which are products associated with or derived from MAST mission data. MAST provides HLSP contributors with permanent hosting of data files, a web page, and where possible, loading of data products into MAST services, making the data more accessible and discoverable. The ASDI services will consist of synthetic data search capabilities and one or more data simulation services associated with a particular mission, instrument, or data type. MAST currently hosts a handful of synthetic data HLSPs that will be added to ASDI services in the future.
If you are interested in contributing synthetic data to MAST, get in touch! We encourage you to familiarize yourself with the HLSP contribution guidelines, and to fill out the HLSP contribution interest form. If you mention ASDI or synthetic data, we will work with you to begin the process.
