skytrackr 2.02025-12-02
Where release 1.0 was tuned for use on the common swift (an ideal light logger species) this release sees improvements in which cover expanding the methodology to species which have less than optimal (noisy) light logger data. It provides new methods to estimate suggested parameter ranges.
The package now provides two modes of calculating a diurnal light profile to fit to the data. The normal, default, “diurnal” mode calculates light levels for a single (static) location (latitude, longitude), while the new “individual” model calculates light levels along a rhumb line track between the last estimated position and a target (end) position. The speed depends on the track length, and is constant throughout. The “individual” model therefore corrects for the slight changes in light levels when moving with or against a changing twilight. Consider the “individual” mode experimental still.
- introduction of a filter function
stk_filter(), but helpful in visualizing data - introduction of the
stk_calibrate()function to estimate scale factors for optimization - correction to the subsetting of the data (see
stk_filter()) to accommodate noisy data - trap rendering error on intermediate plots, which corrupts optimization
- support for a threshold based (twilight) method when only providing a single
rangevalue - support for a new light model through a model parameter, with individual points tracked along a rhumb line instead of using a global light curve fit (single lat,lon value)
