Overflow error in planck.py test #1

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
run the planck.py __main__ function.

results in:
planck.py:139: RuntimeWarning: overflow encountered in square
  (temperature* wavelength ** 5 * (numpy.exp(xx)-1) **2 )

this is probably due to extreme values of temperature and spectral variable 
that results in overflow.

GoogleCodeExporter commented 9 years ago 
Overflow resulted from (numpy.exp(xx)-1)**2.
Refactored the code to prevent overflow.
