[ascl:1503.004] HELIOS-K: Opacity Calculator for Radiative Transfer

HELIOS-K is an opacity calculator for exoplanetary atmospheres. It takes a line list as an input and computes the line shapes of an arbitrary number of spectral lines (~millions to billions). HELIOS-K is capable of computing 100,000 spectral lines in 1 second; it is written in CUDA and is optimized for graphics processing units (GPUs).
