Image Details
Caption: Figure 7.
Selection of the eht-imaging (RML) parameter survey results on real and synthetic data with April 11 EHT baseline coverage. A 2D slice of the 7D parameter space is displayed, corresponding to different weights on the MEM and TV regularizers. All other parameters are kept constant (Compact Flux = 0.6 Jy, Initial/MEM FWHM = 40 μas, Systematic Error = 1%, TSV = 0, and ℓ1 = 0). The left panel shows results of the parameter search on the Crescent synthetic data, while the right panel shows reconstructions for the same parameters on M87 data. Images that meet the threshold for the Top Set are outlined in green. Note that the upper-left reconstruction has no regularization; it is produced by enforcing only image positivity and a constrained FOV.
