Table 1 Extracted crescent parameters for M87*. A comparison of d, w, η, A and fC as defined in ref. 4 Table 7, computed for images published by the EHT Collaboration (first three sections of table) as well as for our reconstruction (last two sections). The fourth section provides the results for the estimators and their s.d. as defined in ref. 4 applied to our posterior mean. The fifth section provides means and s.d. on the basis of processing our posterior samples individually through the estimators and by computing mean and 1σ s.d. from these results.
