Data values

The following fundamental data values are taken directly from the computer code that is generating the mathematics and associated dynamic graphics on this website.

Note : The work on the pyramid is still ongoing and the sensitive calibration system in the gallery is currently adjusted to the 6th decimal place and therefore not fully resolved. The following data is created using the WGS84 reference ellipsoid's flattening and the associated original latitude of the Great Pyramid, which has a variance of 15cm north of the location when calibrated using the gallery. This discrepancy will be resolved in the next version of this work, and the values published below should be taken as being accurate approximations until the point is reached when the gallery has been fully resolved.
