Oktava MK-012-01 hypercardiod microphones, matched pair, calibration protocols below - two coordinate systems, each for one mic, measurements from 20Hz to 20KHz in 0° (top), 90° (center) and 180° (bottom) phases.

How can i scan this and have values read into a text file, like
Freq Vol
20 0,00
23 0,04
...
20000 -12,2

? Is there a software for this type of thing?

Note: for actual speaker calibration I'll use omnis, of course.

@jrp can't think of anything short of a python script with some simple image processing code to sample the curve every X pixels. After correcting for image distortion.

@pedro In order to generate data for frequency diagrams actually this new version is needed: https://www.graphreader.com/v2
