示例1:
# 需要导入模块: from Stoner import Data [as 别名]
# 或者: from Stoner.Data import peaks [as 别名]
d=Data(filename,setas="xy") #Load the low angle scan
#Now get the section of the data file that has the peak positions
# This is really doing the hard work
# We differentiate the data using a Savitsky-Golay filter with a 5 point window fitting quartics.
# This has proved most succesful for me looking at some MdV data.
# We then threshold for zero crossing of the derivative
# And check the second derivative to see whether we like the peak as signficant. This is the significance parameter
# and seems to be largely empirical
# Finally we interpolate back to the complete data set to make sure we get the angle as well as the counts.
d.lmfit(ExponentialModel,result=True,replace=False,header="Envelope")
d.subtract("Counts","Envelope",replace=False,header="peaks")
d.setas="xy"
sys.exit()
t=Data(d.interpolate(d.peaks(significance=sensitivity,width=8,poly=4)))
t.column_headers=copy(d.column_headers)
d%='peaks'
t%='peaks'
d.setas="xy"
d.labels[d.find_col('Angle')]=r"Reflection Angle $\theta$"
t.del_rows(0, lambda x,y: x<critical_edge)
t.setas="xy"
t.template.fig_width=7.0
t.template.fig_height=5.0
t.plot(fmt='go', plotter=pyplot.semilogy)
main_fig=d.plot(figure=t.fig, plotter=pyplot.semilogy)
d.show()
#Now convert the angle to sin^2
t.apply(lambda x: np.sin(np.radians(x[0]/2.0))**2, 0,header=r"$sin^2\theta$")
