jdowell 2012-10-26 15:37 Rev.: 1026

Cleaned up some formattting in drxGPU.py/drxGPUStokes.py. Fixed a bug in the S-K limits calculation used in drxGPU.py. Added hdfGPU.py and hdfGPUStokes.py for writing out to HDF5 files.

Turned off the print statements in drxGPU.py and worked on the spectral kurtosis function in lgp.SpectraStokes by adding an additional control value to the getSpectralKurtosis function that sets the number of FFTs per data chunk. For Stokes I, this value is 2. Updated drxGPUStokes.py to use the S-K values and leave the colorbars linear space.

drxGPU.py inches towards being useful. I found another bug with the GPU memory handling with regards to computing the PSDs.
