Problem 2a

Start by modifying the function dir2cart from Problem set # 2:



In [19]:

Read in the datafile 'demag.dat' in the Chapter_6 folder in the data_files/Essentials_Examples directory that comes with the PmagPy distribution. Copy that folder into the directory with you notebook in it.



In [4]:

    
import numpy as np
data=np.loadtxt('Chapter_6/demag.dat')  # this will load the data. 
# first print it out so you can see what is in data....   
# Put Temperature in Ts and Ints, Decs Incs into their own lists
# check whether you should transpose data to make that easier.  
# then send your data to your dir2cart function.

Problem 2b

For this we just have to normalize the intensities by the first step and re-run dir2cart.

Problem 2c

Now plot X and Y components versus Temperature



In [6]:

    
import matplotlib.pyplot as plt
%matplotlib inline
# plot Temperatures on the X axis and X on the Y axis.
# Then do the same (using different symbols) for Y on the Y axis.  
# add labels for the X and Y axes.
