<p>An option would be to perform a separate query for the NEOs with
the parameters c1_item=Ag&c1_op==&c1_value=Y. The
resulting CSV is 539K big and could be appended to the asteroids
file. I will implement a patch for that. <br>
</p>
<p>I alter the first query, so that no NEOs are returned to avoid
dublication.</p>

Hello all.<br>
<br>
I've just got into KStars development and took on the junior job
"Investigate NEOs".<br>
<br>
Here are my results:<br>
<br>
I've constructed a request to JPL myself and got out a csv of
several hundred megabytes, which is certainly not suitable for
KStars.<br>
<br>
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.<br>
<br>
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'.<br>
<br>
The asteroid (2003 YT1) with an absolute magnitude of 16.2 doesn't
mach the criteria and is not included in the download.<br>
<br>
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.<br>
<br>
One/I could maybe implement a setting for the absolute magnitude
filter, to leave it to the user.<br>
<br>
I am looking forward to feedback! (Maybe I haven't understood
it...)<br>
<br>
Cheers and Thanks!<br>

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