Magnetic declination not being applied

[Rodrigo Severo]

Hi


Please take a look at the attached file. It's a simple test file to see magnetic declination being automatically applied for svx files.

Unfortunatelly it seems that Survex is not applying magnetic declination at all as, according to NOAA Magnetic Field Calculator available at https://www.ngdc.noaa.gov/geomag/calculators/magcalc.shtml , the magnetic declination at the attached file data/location is 22.96° W and the leg I included at the test file, which has a 0° azimuth is shown perfectly vertical in my Aven.

Apparently there is a "*declination auto" command but it asks for 3 numbers after auto. What are they? I can't find a description of what they should be in the documentation.

How can I make Survex apply the proper magnetic declination appropriately?
