CURVE and LSFIT are interactive programs designed to obtain the best data fit to an arbitrary curve. CURVE finds the type of fitting routine which produces the best curve. The types of fitting routines available are linear regression, exponential, logarithmic, power, least squares polynomial, and spline. LSFIT produces a reliable calibration curve for gamma ray spectrometry by using the uncertainty value associated with each data point. LSFIT is intended for use where an entire efficiency curve is to be made starting at 30 keV and continuing to 1836 keV. It creates calibration curves using up to three least squares polynomial fits to produce the best curve for photon energies above 120 keV and a spline function to combine these fitted points with a best fit for points below 120 keV.
