**1. bx - Time series analysis with graphical interface**:

This program provides visualization of time series of 3 component vector time series.
Coordinate rotations including those derived from the data such as minimum variance,
tangential discontinuity, and shock coplanarity. Power spectra, coherence and phase spectra
are calculated. Wave analysis of the real and imaginary parts of the spectral
matrix provide measures of the direction of propagation and the polarization as a function
of frequency as well as the handedness and ellipticity. Hodograms can also be drawn.

**2. mx - Dynamic spectral analysis:**

This program enables the display and analysis of data from multiple stations.
Dynamic spectra of either the time series or its time derivative are permitted. Cross
spectral phase and coherence are provided. Dynamic analysis of the real and
imaginary parts of the spectral matrix are provided, including the dynamic
calculation of the ellipticity and direction of propagation.

**6. xtrans - Coordinate transformation**:

This program allows the transformation of vectors from one geomagnetic
coordinate system to another. It also calculates geomagnetic locations
and local times from geographic location and universal times.
