; cf_plot_rate_linear.pro is a procedure to plot the count rate and screening
; as a function of time for calfuse 3.0 data.
; THIS VERSION PRODUCES A LINEAR PLOT OF COUNT RATE
;
; Author: Edward M. Murphy
; Written: 2000 April 21
;
; Calling sequence: cf_plot_rate3, rootname
;
; Inputs: rootname will have 'idf.fit' added to it.
;
; 02/20/03 JC Hsu Adapt from cf_plot_rate.pro to work on version 3.0 data.
; 05/17/04 V Dixon Adapt from cf_plot_rate3.pro
