Data Fitting Tools

• sddsexpfit -- Does an exponential fit to column data. Example application: finding the exponential lifetime of a beam in a storage ring, or the half-life a radioactive sample.

• sddsgenericfit -- Does generic fits to column data. Example application: fitting the sum of two gaussians.

• sddsgfit -- Does gaussian fits to column data. Example application: finding the width of a resonance, or the rms size of a beam profile.

• sddsmpfit -- Does polynomial fits to multiple columns data, including error analysis. Will do fits to specified orders, fits of specified symmetry, and adaptive fitting. Use sddspfit as a simpler and somewhat more capable alternative for fitting a single column of data.
