These between shell PE-translations were calculated using MI between shell means
PE-translations (mm) relative b0-shell from direct registration to mean b0
Shell 1.5e+03 to b0-shell: PE-translation = 0.267 mm
Shell 2.99e+03 to b0-shell: PE-translation = 0.326 mm

Relative PE-translations (mm) between the shells
Shell 2.99e+03 to shell 1.5e+03: PE-translation = 0.041 mm

Deduced PE-translations (mm) relative b0-shell
Shell 1.5e+03 to b0-shell: PE-translation = 0.267 mm
Shell 2.99e+03 to b0-shell: PE-translation = 0.326 mm
