Junior Job: Investigate NEOs

[Valentin Boettcher]

Hello all.

I've just got into KStars development and took on the junior job
"Investigate NEOs".

Here are my results:

I've constructed a request to JPL myself and got out a csv of several
hundred megabytes, which is certainly not suitable for KStars.

Looking at the differences between my query and the one in KStars, I
found some extra parameters, which had not been included in my one:
c1_item=Ai and c1_op=%3C and c1_value=12.

That basicly means, that JPL filters the asteroids for the ones which
have an parameter 'H' (absolute magnitude) smaller than 12, which means
that they are 'visible'.

The asteroid (2003 YT1) with an absolute magnitude of 16.2 doesn't mach
the criteria and is not included in the download.

The parameter can't be set much higher, because the file size of the
download would increase rapidly and slow down KStars. I tested a
magnitude of 17 with a file size of a bit over 78 megabyte and my laptop
struggled.

One/I could maybe implement a setting for the absolute magnitude filter,
to leave it to the user.

I am looking forward to feedback! (Maybe I haven't understood it...)

Cheers and Thanks!

P.S. Here is a screenshot with 2003 YT1 :). KStars crashed after a while...
