Statement

Methodology:

PTT tags were deployed on eight randomly selected birds roosting at Maiviken ( 11 June 2018) and eight randomly selected birds roosting at Ocean Harbour (18 June 2018). Birds were then released and positions were transmitted via the ARGOS system until the tags expired.

Data quality:

Satellite fixes are between 1.5 and 10km accurate, depending on the accuracy class assigned by ARGOS.

The PTT data files include quality information, under the fields loc_class and loc_ind. The loc_class field indicates an error value for the location which is determined by the number of satellites the tag connected with. Codes are detailed in readme.txt file. The loc_ind field indicates the IQ (Quality indicator). This indicator gives information on the transmitter in terms of X and Y. X (the first digit in the loc_ind field) indicates residual error on the frequency calculation. Y (the second digit in the loc_ind field) indicates transmitter oscillator frequency drift between two satellite passes. Meanings of the values of X and Y are detailed in the readme.txt file.
