syntax:
<missing value tag 1> <missing value tag 2> ... <missing value tag nv>

This line contains a missing value code for each dependent variable in the file.

The number format of the missing value code (number of digits left and right of the decimal point, use of exponential notation or not) specifies the number format of the corresponding data column in the data section. The missing value code is generated by filling all digits with a 9, also for numbers in exponential notation. The absolute value of the missing values code should be at least 1 order of magnitude larger than the largest valid value ever expected.

Examples:

Mg: range 0.001-3.000: 99.999

SO4: range 0.01-20.00: 999.99

Ozone: range 0-250: 9999

end_time: range 0.000000-366.000000: 9999.999999
end_time: range 0-366: 9999

numflag: 0.000000000-0.999890699: 9.999999999
