Research overview:
 
 The paper presents the characterization of a magneto-inductive sensor
 with space applications in mind. The measurement principle of the sensor is ideal for
 small spacecraft applications, allowing for low cost and power consumption functioning
 with measurement capabilities that exceed those of other commercial magnetometers and
 are similar to other sensors specifically designed for small spacecraft.
 
 The research presented in the paper was conducted in 2017 at the Department of Climate
 and Space Sciences and Engineering and the Space Physics Research Laboratory at the
 University of Michigan.
 
Methods:
 
 The data used in the study were collected using a PNI RM3100 magnetometer at a sampling
 frequency of 40 Hz. The data were collected either at the Michigan Moldwin Magnetics Lab
 or at a copper room, both located in the Space Research Building in Ann Arbor, MI, USA.
 The data were collected using a program in C language and analyzed using Matlab.
 
File inventory:
 
 The data are contained in the MagnetometerData.zip file. The compressed file contains
 three separate folders and one file.
 
 The FrequencyResponse folder contains all the files used for the frequency response
 analysis in the paper (section 3.4).
 
 The Linearity_data folder contains the data used for the linearity analysis in the paper
 (section 3.3).
 
 The Sensitivity folder contains the data used for the resolution analysis in the paper
 (section 3.1).*
 
 The stability_data_apr2017.txt file contains the data used for the stability analysis and
 for the noise floor analysis in the paper (sections 3.2 and 3.1 respectively).

 
Variables:
 
  For all the files, the first column corresponds to time (in seconds) since the beginning
  of the sampling and the rest of the columns correspond to the X-, Y- and Z-components of
  the magnetic field (in nT). For the Linearity tests, a fifth column is present, which
  represents the field measured by an external fluxgate magnetometer during the data
  acquisition. For the Sensitivity tests, the last column represents whether the data were
  recorded inside (1) or outside (0) the shield can.

*ADDENDUM June 1, 2018:
