NIST Handbook of Basic Atomic Spectroscopic Data - SRD 108

Data provided by  National Institute of Standards and Technology

This handbook provides a selection of the most important and frequently used atomic spectroscopic data in an easily accessible format. The compilation includes energy levels, ionization energies, wavelengths, line intensities, transition probabilities, and spectrum assignments for the neutral and singly-ionized atoms of all elements hydrogen through einsteinium (Z = 1-99), given in separate tables for each element. It includes approximately 12,000 spectral lines of all elements. Bibliographic references are provided for all data.

NIST Stopping-Power & Range Tables for Electrons, Protons, and Helium Ions - SRD 124

Data provided by  National Institute of Standards and Technology

The databases ESTAR, PSTAR, and ASTAR calculate stopping-power and range tables for electrons, protons, or helium ions. Stopping-power and range tables can be calculated for electrons in any user-specified material and for protons and helium ions in 74 materials.

NIST Observed Interstellar Molecular Microwave Transitions Database - SRD 116

Data provided by  National Institute of Standards and Technology

This database contains critically evaluated transition frequencies for the molecular transitions detected in interstellar and circumstellar clouds reported in the literature through mid-2008. The tabulated transition frequencies are recommended for reference in future astronomical observations in the centimeter and millimeter wavelength regions. The transition frequencies have been selected through a critical examination and analysis of the laboratory spectral data obtained from the literature.

Almanac API - Ranking by Geography Type within the Nation

Data provided by  National Telecommunications and Information Administration

This API is designed to find the rankings by any geography type within the nation with a specific census metric (population or household) and ranking metric (any of the metrics from provider, demographic, technology or speed). Support for full list of rankings by nation is not allowed for geography types (e.g., county, census place, usf) so only the top ten and bottom ten rankings would be returned through the API.

Broadband Summary API - By Geography Type and Geography ID

Data provided by  National Telecommunications and Information Administration

This API returns broadband summary data by geography IDs for a specific geography type. It is designed to retrieve broadband summary data by geography and census metrics (population or households) combined as search criteria. The data includes wireline and wireless providers, different technologies and broadband speeds reported in the particular area being searched for on a scale of 0 to 1.
