SolRaT (Solar Radiative Transfer) is a flexible forward modeling code for non-LTE transfer of 
radiation in stellar atmospheres.

The code provides a multi-level framework for modeling radiative transfer:
1. **Public API** allows to run built-in RT models. Currently, SolRaT ships the non-LTE multi-term atom model ([LL04](#References)) with multiple constant-slab atmosphere stratification.  
2. **Modeling API** allows to extend existing models or create completely new ones.    
3. **SolRaT Engine** introduces a meta-language that allows the user to write a human-readable code that directly 
resembles the underlying the mathematical equations. The user does not need to focus on code optimization, 
as it is handled under the hood. 

#### Key highlights of SolRaT:
- Non-LTE radiative transfer
- Multi-term atom model allows for arbitrary magnetic fields
- Multi-slab atmosphere model allows to explicitly model the atmospheric stratification
- Flexible modeling API allows to adjust the physical model to specific problems
- Platform-independent python implementation
- Uses high-performance libraries (pandas, numpy) that leverage SIMD instruction sets


#### How to run:
1. Install SolRaT from PyPi: ```pip install solrat```
2. Explore the [demos](https://github.com/yakovkinii/SolRaT/tree/master/_demos) and [tests](https://github.com/yakovkinii/SolRaT/tree/master/_tests) for usage examples.
3. Explore the [documentation](https://solrat.readthedocs.io/latest/).

#### Citing:
SolRaT is currently in beta testing. Journal article is pending and the detailed documentation is under development.
