TRANSFER STANDARD S1: Autocollimator before repair

Degrees of equivalence are shown under graphical form on Figures 7.3 and 7.6 on pages 38 and 42 of the EURAMET.L-K3.2009 Final Report for small measuring range (+/- 10 arcsec) and long measuring range (+/-1000 arcsec), respectively.
They are represented as box plots of En values.
