All these resolution charts were copied from "Asahi-Camera New Face Tests, Trajectory of Minolta"
ISBN-02-272146-4 Publisher ASAHI SHINBUNSHA 2001/12/01 in Japan

The each chart consists of two resolution (lpm) tables, top one at lens' wide open performance and bottom
one at f5.6 or f8 performance. Each of those tables possibly has two 'rows', top one shows the best
at the centre, bottom one shows at when the entire frame's averaged performance is the best.

Each 'row' has two lines, top Rr for sagittal resolution and bottom Rt for tangential resolutions,
and the first is for the centre, next ones are for from centre to corner in mm, then the last one
is their average in the entire frame. If the average of entire frame is over 100, the lens should be
considered a pretty good one when these lpm (lines per milli-meter) was measured before MTFs.
Some of them have only one line, which means there is no difference between the best centre and
the best averaged performance. MC Rokkor 28/2.8 is its typical example, there is no focus shift.
