Active region updates with GPU
1: for ttimestep = 1, 2,…, T do |
2: for nregion = 1,2,… N do |
3: Localize(lat, long, i, ph). |
4: if Localize = 1 then |
5: Updating InfoMap(xn,yn) = the type of active region. |
6: end if |
7: end for |
8: Inject velocity velX,Y with GPU fast interpolation for the active regions in the information map. and derive S′active (λ). |
9: Weight S′active(λ) by limb-darkening intensity IX,Y |
10: Use Eqs. (1)–(3) to calculate the difference of each effect |
11: Compute summation of ∆S′(X,Y) for each effect. |
12: Use Eq. (4) to derive the final spectrum at tT. |
13: Lower the resolution of final spectrum at tT to match the HARPS-N observation. |
14: end for |
