SVN commit 732725 by harris:

Linear interpolation for refraction correction.

We use a lookup table to determine the correction due to atmospheric
refraction for an object's apparent altitude as a function of its true
altitude.  Until now, we adopted the correction value from the nearest
altitude position in the lookup table.  This breaks down near the
horizon because the correction changes rapidly with altitude,
resulting in large discontinuous "jumps" as an object's altitude
carries it between positions in the lookup table.

Now, we are using linear inerpolation to ensure that the refraction
correction is a smooth function of the true altitude.

TODO: doing linear interpolation is more costly than a straight table
lookup.  It might make sense to only interpolate near the horizon,
where the corrections are large and changing rapidly with altitude.
The straight-lookup strategy should be fine above some threshhold
altitude.

SVN commit 732841 by harris:

Display apparent altitude, not true altitude in statusbar and details
dialog.

Also, added some debug code: when you press "Q", it dumps a series of
angle values, followed by their value after refraction correction,
followed by the value after the inverse correction.  The values in
columns 1 and 3 are not quite the same; they differ by up to a few
arcseconds.

TODO: SkyObject::riseSetTime() does not take refraction into account,
so if you right-click on an object that is just above the south
horizon, the popup menu may indicate that it never rises!

SVN commit 735399 by harris:

Modifications in preparation of removing ExtDate and friends.
KStarsDateTime now depends on the new KDateTime class, which covers
dates -4713 to 11,000,000.  So there's a slight regression in the fact
that we used to be able to go back to year -50,000.  This should
eventually be fixed, but for now I'm using the regular KDateTime
range.

I need to remove ExtDate because it's based on Qt-3.x code, which is
necessarily licensed under GPL v2 only.  KDE is migrating to GPL v3,
which is not compatible with GPL v2.

I also fixed the layout of the AltVsTime tool, which involved
splitting the AVTPlotWidget into its own files, so that Qt designer
could properly use it as a promoted widget.

TODO: make sure all time-related functions work properly.  One thing
to watchout for: KDateTime uses UT by default, so some parts of the
code where local time was assumed needed to be changed.  I may have
missed some of these.

In the ObsListWizard, I need to enable the feature that allows the
user to select objects observable from a given location, on a given
date.

SVN commit 735406 by harris:

Remove the ExtDate library.  It can't remain, because much of it is
based on Qt-3.x code, and therefore licensed under GPL v2 only.  KDE
is migrating to GPL v3, which is not compatible with GPL v2.

KStars is already ported to use the new KDateTime classes.  AFAIK, no
one else is using ExtDate (there is some usage in extragear, but those
programs use their own local fork of extdate).

TODO: After removing extdate, there are no more widgets defined in
libkdeedu/widgets.  We could remove this directory, but I've left it
in for now in case we add widgets at some future date.

What does it mean for those of us who don't want to move to GPL v3?

If your GPL v2 license is unmodified (i.e., it contains the phrase "(at your 
option) any later version"), then there's no problem.  The incompatibility 
arises if you've modified the license so that only GPL v2 is allowed.

In that case, I'm not sure what the options would be.  At this point, we have 
no such code in KStars.

Jason

That's alright then. I was afraid we would have to release the source code as 
GPL v3 only (or GPL v.3 or later). With the headers unchanged, the user can 
decide which license to pick. INDI will remain the same, LGPL v2.1 or later.

Catalogs from Stellarium

Hi,
Stellarium made  huge progress. Version 0.9.0 can display stars up to
18 magnitude. They are using own compilation of NOMAD catalog, it
should be more precise then USNOA 2.0.

More details at: http://www.stellarium.org/wiki/index.php/Stars

Maybe you can support this catalog at KStars? C++ code for reading
this format is at src/StarMgr.cpp

Thanks,
Jan Kotek
