Key:

  - Date/Time: UTC time. If this observation is used in the track it is marked with a "*". If it is used for its own 30-minute window, it is put in bold.

  - Source/sensor: Satellite source of the analyzed image.

  - Vmax: Maximum winds listed in the forecast center analysis/forecast, *not* ARCHER.

  - ARCHER lat/lon: Coordinates of the ARCHER algorithm, valid at the time of the observation. If no center fix could be found, then it is "***".

  - Geo ref lat/lon: Coordinates of the ARCHER algorithm, valid at the time of the *nearest geo image*.

  - 50% cert. rad.: Radius of the circle (in degrees) that defines the area in which the ARCHER center of rotation is 50% certain. The lower the number, the more certain the position.

  - 95% cert. rad.: Radius of the circle (in degrees) that defines the area in which the ARCHER center of rotation is 95% certain.

  - Eye diam (deg): ARCHER-resolved eye diameter (in degrees). Green: robust, yellow: less certain, red: not robust.

  - % cert. of eye: Percent certainty that an eye exists in this image, determined by ARCHER. Currently only available for IR and 85-92 GHz imagery.
