FRED / ALFRED vintages

core.fred_observations

MIXED LICENCE. Holds the ICE BofA credit spreads, which may not be redistributed, alongside the ALFRED Tier A macro series, which may. Export is filtered per row on `source`; browsing is not.

This table holds sources under different licences. The CSV contains 134,191 of 138,259 rows; fred_ice_oas is excluded. Browsing here is not redistribution — exporting is.

observation_date leads no index, so this sort reads every matching row and keeps only the top 1,300 in a heap (the page LIMIT), under a 5s statement timeout.
