**graph tool.**Pop up a new graph*Tv*for current use.**rdist.**Graph the radial residula errors in the graph*Tv*. Left camera residuals are in red and right camera residuals are in blue. Any effects due to radial distortion will manifest themselves as a systematic curving of these distributions. With a small amount of experience this plot can be used to visually varify the adequacy of a calibration.**epi-err.**Plot a histogram of errors perpendicular to the epi-polars. As this measure is completely independent of 3D model assumptions, this distribution can be used to estimate the mean location accuracy of calibration features.**x-err.**Plot a histogram of errors in the x direction (and therefore approximately along the epi-polars).

Additional information regarding statistical distributionc can also
be viewed in the **Histogram Tool**.

The additional fucntionality is also provided.
