Ervin, Tamar; Halverson, Samuel; Burrows, Abigail; Murphy, Nei; Roy, Arpita; Haywood, Raphaelle D.; Rescigno, Federica; Bender, Chad F.; Lin, Andrea S. J.; Burt, Jennifer; Mahadevan, Suvrath
SolAster provides querying, analysis, and calculation methods to independently derive 'sun-as-a-star' RV variations using SDO/HMI data for any time span since SDO has begun observing. Scaling factors are provided in order to calculate RVs comparable to magnitudes measured by ground-based spectrographs (HARPS-N and NEID). In addition, there are routines to calculate magnetic observables to compare with RV variations and determine what is driving Solar activity.
