You can use the DISPLAY FLUX button in the editor/analyzer to see a graphical representation of the flux data.
How the bits are encoded/decoded to/from FM/MFM/GCR to/from flux is different for each type of format. For example, low density MFM has 3 different duration periods, so each duration will have a bit value of either 1, 01, or 001 (4us/6us/8us). You pack the bits together to make up your MFM bytes. FM is just a 0 or 1, based on the duration. I guess with FM you have to ignore every other bit when decoding from FM to standard data. Your data is definitely FM because it only has 2 different duration periods.
