# A Statistical Examination of the Radial Line Azimuths at Nazca

Clive L. N. Ruggles, 1990. _The Lines of Nazca (American Philosophical Society, Memoirs 183)_.

Tests the line azimuths against solar, lunar and stellar targets and finds no significant astronomical patterning beyond a weak solstitial tendency.
