 """ NAME atrm_magic.py DESCRIPTION Converts ATRM data to best-fit tensor (6 elements plus sigma) Original program ARMcrunch written to accomodate ARM anisotropy data collected from 6 axial directions (+X,+Y,+Z,-X,-Y,-Z) using the off-axis remanence terms to construct the tensor. A better way to do the anisotropy of ARMs is to use 9,12 or 15 measurements in the Hext rotational scheme. SYNTAX atrm_magic.py [-h][command line options] OPTIONS -h prints help message and quits -f FILE: specify input file, default is atrm_measurements.txt -fsp FILE: specimen input file, default is specimens.txt (optional) -Fsp FILE: specify output file, default is specimens.txt (MagIC 3 only) -DM DATA_MODEL: specify MagIC 2 or MagIC 3, default is 3 INPUT Input for the present program is a TRM acquisition data with an optional baseline. The order of the measurements is: Decs=[0,90,0,180,270,0,0,90,0] Incs=[0,0,90,0,0,-90,0,0,90] The last two measurements are optional """
