libdeco-ostc provides a library for dive decompression calculation. The library functions perform dive simulation using OSTC dive computer firmware and return decompression schedule information. The decompression model used is Buhlmann (ZH-L16C) with Gradient Factors. A C API (libdeco library) and Python API (DecoMecha module) are supported.
decotengu is a dive decompression library to experiment with various implementations of the Buhlmann decompression model with Erik Baker’s gradient factors. The results of decotengu calculations are decompression stops and tissue saturation information. Third party applications can use those results for data analysis purposes or dive planning functionality.
