The online service saves data in the TAGS forma. The fields `excluded` and `interp` may have values of `TRUE` only for `twilight > 0`. * `interp` - indication of whether the light value at twilight was interpolated (logical, `TRUE | FALSE`).
INTIGEO LIGHT LOGGER MANUAL
* `excluded` – indication of whether a twilight was excluded during manual inspection (logical, `TRUE | FALSE`)
INTIGEO LIGHT LOGGER SOFTWARE
* `twilight` – assigned by the software numeric indication of whether the record belongs to sunrise (1), sunset (2) or none of those (0) * `datetime` – date and time in ISO 8601 format e.g. A TAGS file is a CSV file containing the following fields: An example of the routine for the twilight definition in BAStag is available as () to (#rakhimberdiev_jab_2016).įLightR works with the ‘TAGS’ format, which is an agreed general annotation of twilight data by National Centre for Ecological Analysis and Synthesis working group ‘Establishing an open-source animal-tracking analysis platform for archival geolocators. when a bird enters or exits a cavity during twilight ((#rakhimberidev_jab_2016)). In this software, user guides semi-automatically search for the twilight times and then visually explores the light data, manually removing twilights defined apparently wrong or around which the light pattern is atypical or systematically biased, e.g. BAStag, twGeos or GeoLight (#lisovski_2012a), or online service for this purpose.
