Steamboat - density plot and post-back data

[907Resident]

There are two small issues with the NGBN_STMB_12Jun2019.m script:

1. There is an issue with printing the density plot. Likely, there are too many NaN entries in the ChamON variable.
2. Due to the fact that this set of measurements was collected from an ongoing time series, there are no "post-back" (background) data since that is actually the pre-back for the next measurement in the series. The associated code is commented out and needs to be confirmed that it can be removed

Complete this issue by:

• [ ] printing the density plots
• [ ] removing commented out post-back code
• [ ] confirming the script runs with all changes made
