of point transfer with the AP/C-5
.1
Some few trials have been made to determine the
accuracy of point transfer* For comparison purposes
in the first test the accuracy of a signalized point
point somewhere in the field was selcted and x- and
yt-parallaxes have been cleared. In the third test, the
same natural point was taken, but Dove prisms were
used to clear y-parallaxes.

are nearly the same*

dove prism. There is a meaningful difference between
standard deviations sx and sy.

with dove prism. X~parallaxes remained constant.
