    Hi Greg,

    Ah, I see, you're sampling the projection along the x axis of the sensor (long axis). Just for fun I took the WCS (with distortion polynomial) in the FITS header and sampled it the same way, at x values 3000-d/2 and 3000+d/2 for d from 100 to 6000. Attached are the plot and table (I took the liberty of typing in your cheat sheet). Pretty good agreement.

    Cheers,
    Peter
