PEC with MX
Peter,
I am not sure I understand exactly your question but this may cover it.
The recorded text file includes the RA index for each point. So if you plot the RA index against the PE error you can see at which index values the error is a maximum.
I previously used the maximum positive error but the maximum negative error might be clearer to see on the excel sheet.
In both cases the maximum negative error is very close to 600 but when loaded to the mount the maximum positive correction is applied at about 800 for A and about 100 for B, not at 600. (The horizontal scale on the mount plot being 0 to 1000.)
Based on this my assumption is the error in the phase is made in the making of the correction curve not during the acquisition.
Regards
Kim
