Comments referenced by line numbers 1. The header shows which computer program was used GAGE the date and time of the calibration. The date is recorded in the MAP file. 3. Block size and operator are identified and later recorded in the MAP file. 4. Block IDs are given here. The S and C blocks are NIST master blocks. The X and Y blocks are shortened forms of customer company names represented here by strings of Xs and Ys. The ID of the comparator used in the calibration F4 is also given and recorded in 85 the MAP file. 9-20. These lines provide the comparison data at ambient temperature and corrected to 20 C using the thermal expansion coefficients in lines 30-34
