 # Surya-Bench Coronal Field Extrapolation Task
 
-This foundation model task uses the foundation model to emulate the physics-based ADAPT-WSA PFSS code, driven by SDO/HMI observations. The parameters to predict are spherical harmonic coefficients which represent the magnetic potential for a domain between the photosphere and te source surface (set to 2.51 Rs).  Included in these FITS files are other variables relating the WSA output that might be useful, such as photospheric polarity and open/closed field line masks.  The ADAPT-WSA code is an ensemble model. Data is included here for all 12 realizations (identified by `R000` - `R011` in the file names).

 Spherical harmonics can be found in fits HDU index 3 (zero-based), as a (2, 91, 91) array. Each (91, 91) array is a triangular matrix with unused elements left as zero.
