Totally 2 bugs were found in Chapter 6:
  1. On p.91 line 8 from the bottom of the 'FRSNL.m'.

    FN=1.525; FK=0.0441;

    should change to
    FN=1.515; FK=0.165;

    The old data are for glass and in this subroutine, values should use clear PE data.

    FN and FK values of glass, clear PE and other glazing were listed in Table 5.1, p.71, of the textbook.

  2. On p.92 line 12 from the bottom of the 'FRSNLa.m'.

    The line of
    FN=1.525; FK=0.0441;

    should be deleted
    for this subroutine did not involve these 2 variables in the calculation.
