Python get_xpos Examples

Example #1

File: qcalc_test.py Project: JeanBilheux/RefRed

 def test_xpos(self):
   self.ds.dpix=220.
   self.ds.dangle=self.ds.dangle0
   self.ds.sangle=0.5
   self.ds.xydata[:, 180:211]+=50*exp(-0.5*((arange(31)-15.)/2.)**2)
   x_pos=get_xpos(self.ds)
   self.assertAlmostEqual(x_pos, 195., places=8)

Example #2

 def test_xpos(self):
   self.ds.dpix=220.
   self.ds.dangle=self.ds.dangle0
   self.ds.sangle=0.5
   self.ds.xydata[:, 180:211]*=1.+5.*exp(-0.5*((arange(31)-15.25)/2.)**2) # reflected beam
   self.ds.xydata[:, 220:251]*=1.+1000.*exp(-0.5*((arange(31)-15.25)/2.)**2) # transmitted beam
   x_pos=get_xpos(self.ds)
   self.assertAlmostEqual(x_pos, 195.25, places=1)
