The maximum likelihood estimating algorithm for complexion measurement of the relative coordinates and distance was created. the most efficient use of heterogeneous data sources is allowed. The accuracy of the algorithm is investigated in two ways: analytically and by numerical simulation. The applicability of the analyses is given. https://www.roneverhart.com/Gretsch-G5210T-P90-Electromatic-Jet-Two-90-Single-Cut-Electric-Guitar-w-Bigsby-Mako-p23063/
