added smooth to filter noise

 
In [6]: PySpectra.calc.smooth?
Signature: PySpectra.calc.smooth(name=None, nameNew=None, box_pts=7)
Docstring:
smooth <scanName> [<newScanName>]

moving average box algorithm: 
  def smooth(y, box_pts):
      box = np.ones(box_pts)/box_pts
      y_smooth = np.convolve(y, box, mode='same')
      return y_smooth

and smothSG (Savitzky-Golay) to filter noise

 
In [11]: PySpectra.calc.smoothSG?
Signature: PySpectra.calc.smoothSG(name=None, nameNew=None, window_size=7, order=3, deriv=0, rate=1)
Docstring:
smooth <scanName> [<newScanName>]
  uses Savitzky-Golay to filter noise

  for details see: PySpectra.calc.savitzky_golay? 


In [11]: PySpectra.calc.savitzky_golay?
Signature: PySpectra.calc.savitzky_golay(y, window_size=7, order=3, deriv=0, rate=1)
Docstring:
Smooth (and optionally differentiate) data with a Savitzky-Golay filter.
The Savitzky-Golay filter removes high frequency noise from data.
It has the advantage of preserving the original shape and
features of the signal better than other types of filtering
approaches, such as moving averages techniques.
Parameters
----------
y : array_like, shape (N,)
    the values of the time history of the signal.
window_size : int
    the length of the window. Must be an odd integer number.
order : int
    the order of the polynomial used in the filtering.
    Must be less then `window_size` - 1.
deriv: int
    the order of the derivative to compute (default = 0 means only smoothing)
Returns
-------
ys : ndarray, shape (N)
    the smoothed signal (or it's n-th derivative).
Notes
-----
The Savitzky-Golay is a type of low-pass filter, particularly
suited for smoothing noisy data. The main idea behind this
approach is to make for each point a least-square fit with a
polynomial of high order over a odd-sized window centered at
the point ...
