Upper & lower limits for SU #1
Description
As Mike suggested, and is also listed in Table 2 of the template,
we had better estimate both upper and lower limits for SU.
I provided preliminary details of calculation in su.ipynb.
Further improvements are necessary for us to check the results.
Same with data storage.
PS: It seems that Table 3 asks for total space, so I simply calculated that on commit ac22b21
