Some key differences
====================

* No longer tied to a single input and output file, can load as many SDFITS files as RAM allows

* No longer tied to a finite number of data containers, you can have as many ScanBlock/Spectrum objects as RAM allows

* Python allows for well-trackable local and global variables





Rough equivalents
=================

In the tables below, it is assumed you have executed the following commands in Python:

`from dysh.fits.gbtfitsload import GBTFITSLoad`
