The most productive Islamic observatory was that erected by the Timurid prince Ulūgh Beg at Samarkand about 1420; he and his assistants made a catalog of stars from observations with a large quadrant.
There are different types of earthquake forecast models, all of which are related to specific sets of observations (e.g., catalogs of seismicity, fault maps, strain rates, and seismic precursors).
L3 - Level 3 products consist of catalogs and aggregate analysis of large numbers of observations.
The result was a system of astronomical observations and records unparalleled elsewhere, thanks to which there are, today, star catalogs and observations of eclipses and novae that go back for millennia.
In "Biological Exuberance: Animal Homosexuality and Natural Diversity" (St. Martin's Press, 1999), Dr. Bruce Bagemihl, a biologist, catalogs scientific observations of homosexual or transgender behavior in 190 species, but says it has been documented in 450 species.
Chandra Source Catalog: The most comprehensive catalog of sources detected in public Chandra Observations.
Also, 18 notebooks of Verdi Burtch's and Clarence Stone's bird observations and a catalog of bird and plant photographs arranged by species.

The stress inversion was performed using previously known data (Global CMT catalog, Ghose et al. (1998)) and solutions derived in this study (total no. of observations: 109).
If observers are not prepared with valid configuration and catalog files, observations cannot be made.
