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 and Table Access Protocol (TAP) service.
There are similar documents for the Emission Spectroscopy and other archive data tables. The full list is located in the Documentation Index (expand Data Documentation and then the Table Column Definitions sub-menu).
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
Digital Object Identifier
If you use archive data or services for your research, please include the following Digital Object Identifier (DOI) as part of your acknowledgment:
DOI 10.26133/NEA10
See Acknowledging the Archive for dataset-specific language. See the full list of NASA Exoplanet Archive DOIs for other data sets and services.
