Input data commands
Program TRC_QNUMB_MAUZ calculates the track alignment quality of a track
written in mauz-format.
The alignment quality is measured in a so called Q-number defined by Banverket, Sweden.
The definition of the Q-number is defined in BVF 541.60 written by Banverket, Sweden.
A short description of the Q-number is given in this manual under
- Read the Mauzin-registration written in *.mauz-format.
- Calculate the Q-number according to:
| 2.1.1 || High pass filter column #1 and #2 in a FIR-filter according to fig. 10.6 in BVF 541.60 written by Banverket.
| 2.1.2 || Calculate the average value of column #1 and #2.
| 2.1.3 || Calculate the standard deviation of the average value, the standard deviation σH.
| 2.2.1 || High pass filter column #5 and #6 in a FIR-filter according to fig. 10.8 in BVF 541.60 written by Banverket.
| 2.2.2 || Calculate the standard deviation of the lateral irregularities. The lateral track irregularity signal is the best column of #5 and #6.
| 2.3.1 || High pass filter column #3 in a FIR-filter according to fig. 10.7 in BVF 541.60 written by Banverket.
| 2.3.2 || Calculate the standard deviation of the cant errors.
| 2.4.1 || Add the two signals in phase, lateral errors and cant errors.
| 2.4.2 || Calculate the standard deviation of the sum, the sum is denoted σS (samverkan).
| 2.5 || Calculate the Q-number per kilometer according to the following formula:
| σH ||and || σS ||= || Average standard deviation for "vertical" and "samverkan" errors
| σHgr ||and || σSgr ||= || Comfort limits for the track alignment in actual class.

Input data commands
Input data is read in free format, valid separators between the input values are <space>,
<comma>, <tab>, <equal sign> or <carriage return>.
The commands can be written both in lower and upper case letters.
The operation of the program is controlled by the commands
described below; some of the commands also need arguments.
- Track data file written in trac- or trax- format.
Declared= Character*132 Default= Blank
- Length of track sections for which evaluation of standard
deviation and Q-numbers will take place.
Declared= Integer*4 Default= 200
