Findings
Effective retrieval of extinction data using SQL queries
Support for multiple survey datasets including VVV DR2
Demonstrated applications in astrophysical analysis
Abstract
A brief set of notes about the database design for 3D maps of dust extinction in the WFAU Archives, which support data from UKIRT-WFCAM, VISTA and VST. The notes also detail typical use cases, such as getting colour-excesses, extinction-corrections, spectral energy distributions and colour-magnitude diagrams and demonstrate the SQL queries to return data, along with examples from VVV DR2 with bulge extinction maps from Chen et al. (2013).
