in this thread, I shall report on the status of my work on
10000+ galaxies from Steinicke's NGC/IC precision
catalog. For the time being the displays are based on Toti's
galaxy patch with an increasing number of modifications
by myself.
-- I now have derived the general and exact
transformations that automatically produce the correct
orientations of all 10000+ galaxies from a few catalog
parameters (d/D and position angle)!
-- for elliptical galaxies, I assumed a spheroidal
shape (rather than the circular pancake shape in case
of spirals) with dimensions according to the elliptical
subclass number int(10*(1-d/D)). This procedure emerged
in discussions with Selden.
-- I am desperately waiting for Toti's programme code with
which he generated the various galaxy templates, since a
number of them have flaws: like incorrect orientation of the
bars for SBx galaxies or a mirrored sense of rotation of
the spiral arms.
-- the appearance of elliptical galaxies can be dramatically
improved (so don't worry)
-- the next 3 comparisons with actual DSS survey
photos illustrate the high precision in orientation and
shape that my transformations have reached already!
I shall only report back in the forum once Chris
has managed to restore a decent forum performance,
since otherwise this costs too much time for me.
Sorry.
