At a D02.01 Working Group meeting held on Thursday, Dec. 7, 2017, a meeting attendee Mr. Rudolf Terschek of Rofa made a presentation in which graphs were shown from data taken from D2700s, Table A4.9. Barometric Pressure vs Cylinder Height Correction. It was apparent in these graphs, where the ordinate was Digital Counter Correction and the abscissa was Barometric Pressure, that a reasonably smooth line should go through all of the data points of this graph of the Figures. It is clear that there are three errors in Table A4.9 which appear to be typographical. It was suggested that a mistake was made likely during typing (many years ago), and the table value at 22.9 in.Hg should be 297 not 296, at the table value of 24.2 the Digital Counter Correction should be 242 not 243, and the table value at 27.0 should be 0.088 in. not 0.086 in. The objective of this ballot is to correct these errors.
