Comments

Comments are useful to give additional information to human readers, but are not evaluated during file reading.

The following example contains several types of legal comments:

 // This is a discrete version of PREM
 // values at lower side of moho are computed for 24.40001km
 !name PREM // Preliminary Reference Earth Model
 0.000 5.80000 3.20000 2.60000 1451.91656 600.00000
 15.000 5.80000 3.20000 2.60000 1451.91656 600.00000
 15.000 5.80000 3.20000 2.60000 1451.91656 600.00000
 24.400 6.80000 3.90000 2.90000 1345.91217 600.00000
  Moho # here begins the mantle
 24.4   8.11062 4.49100 3.38075 /* I have deleted Q factors here
 40.000 8.10097 4.48526 3.37905
 60.000 8.08861 4.47789 3.37688

The first two lines will be ignored completely. The model name will be identified as "PREM", the name of the discontinuity at 24.4km as "Moho".

The following example demonstrates several types of (currently) illegal commenting:

 /*
