Claim 11:
12. A non-transitory computer readable recording medium having recorded thereon a tolerance error estimating program for estimating a tolerance error of a rotation drive axis of an X-ray analysis apparatus, the program making a computer execute processes of:
obtaining a centroid position of an absorption coefficient as a specific position of a reference sample at each rotation driving time from X-ray detection images acquired by setting the reference sample formed as a sphere of uniform density so that the centroid of the reference sample coincided with the center of a rotation drive shaft, and
calculating the deviation amount Δx in the x direction and Δy in the y direction of the center position of the rotation drive shaft as the rotation drive axis at each rotation driving time from the reference position based on the specific position, when z direction of an orthogonal coordinate system fixed to a sample is set the direction parallel to the rotation drive axis.
