Bases: object

Synthetic diagnostic for producing synthetic frequency/k-spectra from gyrokinetic simulations

Steps: # 1. Inputs are diagnostic specific (diagnostic, filter, k, location, resolution, local rhos). See example_syn_hk_dbs.py # 2. Load equilibrium, kinetics files. Find scattering location theta. See __init__ in class SyntheticHighkDBS # 3. Map (kn, kb) to (kx, ky) for all k’s / channels specified in 1. See function mapk # 4. Load GK output data (fluctuation moment file). See function get_syn_fspec # 5. For each input condition (eg. for each k in DBS/highk), filter sim data. See class Filter, functions apply filter, get_syn_fspec # 6. Generate synthetic spectra and make plots. See functions get_syn_fspec, plot_syn
