The header line of each file contains a three-variable string. Its meaning is unclear. The header lines are removed before data analysis. The remaining columns of the .lig files are: ,
,, where indicates whether the data is ok or suspect
is the time stamp is another way of representing the time; it is the number of seconds elapsed since the reference chosen when the file was processed is the maximum light (0-64) value measured during the previous 2 minutes. Errors are also reported on separate lines (if they are present) with `error` instead of `ok` in the first position of the entry. 1. File List : A.

These two files are from the same individual warbler marked in subsequent years (2013 & 2014). 3. Additional related data collected that was not included in the current data package: n/a 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: We collected these geolocator data from adult male Golden-winged Warblers (Vermivora chrysoptera) from April 2013 to June 2015. Geolocator marking methods manuscript: Streby, H.M., T.L. McAllister, S.M. Peterson, G.R. Kramer, J.A. Lehman, and D.E. Andersen (2015). Minimizing marker mass and handling time when attaching radio-transmitters and geolocators to small songbirds. The Condor: Ornithological Applications 117:249-255. Lack of geolocation effects manuscript: Peterson, S.M., H.M. Streby, G.R. Kramer, J.A. Lehman, D.A. Buehler, and D.E. Andersen (2015). Geolocators on Golden-winged Warblers do not affect migratory ecology. The Condor: Ornithological Applications 117:256-261. 2. Methods for processing the data: Geolocators deployed on Golden-winged Warblers measured ambient light levels every 1 minute and permanently recorded the maximum light reading every 2 minutes for the life of the unit. Compressed data stored onboard individual units were downloaded upon recovery using BASTrak Software (Biotrak, Wareham, UK). The compressed (.txt) file was decompressed using BASTrak Software and we provide the resulting raw light files (.lig). 3. Instrument- or software-specific information needed to interpret the data: .lig files are often read in R using the BAStag package (Wotherspoon et al. 2013). See Kramer et al. (2017) for details on analysis of these raw light-level data. **Wotherspoon, S., M. Sumner, and S. Lisovski (2013). BAStag: Basic data processing for light based geolocation archival tags.
