↑ Note that the flag ratio (B/A in the diagram) is not absolutely fixed. Although the diagram in Executive Order 10834 gives a ratio of 1.9, earlier in the order is a list of flag sizes authorized for executive agencies. This list permits eleven specific flag sizes (specified by height and width) for such agencies: 20.00 × 38.00; 10.00 × 19.00; 8.95 × 17.00; 7.00 × 11.00; 5.00 × 9.50; 4.33 × 5.50; 3.50 × 6.65; 3.00 × 4.00; 3.00 × 5.70; 2.37 × 4.50; and 1.32 × 2.50. Eight of these sizes conform to the 1.9 ratio, within a small rounding error (less than 0.01). However, three of the authorized sizes vary significantly: 1.57 (for 7.00 × 11.00), 1.27 (for 4.33 × 5.50) and 1.33 (for 3.00 × 4.00).
↑ In the 9th edition of the Standard Color Card of America, "White", "Old Glory Red", and "Old Glory Blue" were, respectively, Cable No. 70001, Cable No. 70180, and Cable No. 70075. The Munsell renotation coordinates for these were taken directly from the Reimann et al. paper, the CIELAB D65 coordinates were found by converting the xyY values in that paper to be relative to CIE Illuminant D65 from Illuminant C using the CAT02 chromatic adaptation transform, and relative to a perfect diffuse reflector as white. The "relative" values in the table were found by taking Cable No. 70001's luminosity to be that of the white point, and were converted to D65 or D50 also using the CAT02 transformation. The values for CMYK were found by converting from the CIELAB D50 values using the Adobe CMM and the GRACoL 2006 ICC profile in Adobe Photoshop.
