Data Columns in the Transmission Spectroscopy Table

The following table lists all of the data columns in the Transmission Spectroscopy table (transitspec) when using the interactive table.

There are similar documents for the Emission Spectroscopy, Confirmed Planets, Kepler Objects of Interest (KOI), and Threshold-Crossing Events (TCE) tables. The full list is located in the Documentation Index (expand Data Documentation and then Table Column Definitions).

Some data include more specific information that can also be retrieved as separate columns when pre-filtering interactive tables with URL-based queries. These include:

  • Uncertainties (positive and negative)
  • Displayed String Name (as the value appears in the interactive table)
  • Limits
