NSTX GPI data: fusion experimental data
=======================================

Note: Please contact Michael Churchill, PPPL (rchurchi@pppl.gov) before publishing any results 
with this data set. This data should be shared only among CoDAR project team members. 

This is a fucion experimental data from NSTX, PPPL, called GPI (Gass Puff Images).

This data is captured by high-speed GPI camera. Each image is 64x80 size and there are 369357 iamges.

The data is written in Adios and contains a few variables. Among many variables, `gpiData` is 
the data for GPI images.

bpls (Adios's utility) will print the following information.
