Atmospheric Response Matrices

Precomputed atmospheric response matrices are available for altitudes between 25.5 - 40.5 km, in 1 km steps. Each response file was generated using 10 million photons. Note that these response matrices use the first representation, as discussed in Karwin+24, and they are integrated over all azimuth angles. The files are available on wasabi, and they can be downloaded by using the following command line prompt:

The general file name is atm_response_[alt]p5km.hdf5, where [alt] should be replaced by an integer value between 25 - 40.
