Earth-scattering induced modulation data for low-threshold dark matter experiments

Dark matter particles with sufficiently large cross sections can interact with the bulk matter of the Earth and scatter before reaching a detector. This would induce a modulation signal with the period of a sidereal day.  We calculate these distorted velocity distributions for sub-GeV dark matter particles that interact with a heavy or ultralight dark photon mediators in silicon, xenon, and argon-based detectors. This data set consists of the calculated distorted velocity distributions, as well as the modulated rates used in our study. This data set was used to investigate the properties of a modulation signal, as well as provide projected sensitivities for experiments searching for this effect. We find that searching for a modulation signal can probe new regions of parameter space in regions where experiments typically have been limited by backgrounds. 

Methods
The data here consists of simulated velocity distributions using DaMaSCUS (https://github.com/temken/DaMaSCUS) as well as analytic approximations with Verne (https://github.com/bradkav/verne), for both the heavy and light mediator cases. It also includes rates calculated with https://github.com/ande8412/DarkMatterRates). This data set is meant to be concurrently used with the latter github repository, as it contains all the calculations used in our paper. 

To use this, paste the contents of the "modulated" folder in the halo_data folder in the DarkMatterRates github repository, and paste the contents of the "rates" folder inside the directory modulation_study of the same repository. Further instructions are contained in the repository itself.
