Script to visually indicate what night-time data we have

[hughbg]

Generate this from the hickle files or some code in plot_waterfall could be used to get the LSTs at night.

Have a table with the first column as file name and the second column a horizontal line indicating the hours of night time data. The second column is aligned so we can see what overlap there is. Like:

File 1 0-----------------------24
File 2 0 ---------- 8

Take a look at get_data_summary.py and see what you think. The script outputs a a summary every half hour with:

• | for >90% of data available,
• / or \ for >0% and < 90%, and
• for 0%.
