Fixed another bug in my parsing of the original Espenak data for moon nodes. Added verification that my own Moon calculations match his: The Moon is always within 0.182 arcminutes ecliptic longitude of the node when he says it is crossing the node. The Moon is always within 1.54 arcminutes of the equatorial coordinates he says.
Test data for moon node calculations
The original test data comes from Fred Espenak's
Node Passages of the Moon Table.
I saved the HTML of that page and hand-edited it to create the file espenak_nodes.txt.
Then I wrote the script parse_moon_nodes.py to transform the data into something
easier for my test programs to process. The result is moon_nodes.txt.
