<div class="moz-cite-prefix">Btw., if that is interestting, I have
also written a scipy-only-dependency implementation of
Tepper-Garcia (2006) Voigt profile approximation, if that could be
of interest for e.g. the modeling module or maybe a spectools
module.<br>
<br>
The upside to it is it is precise and is expressed in terms of
physical units - column density and broadening parameter - and
hence can be fed directly to software like e.g. VPfit, and it is
easdily interpreted. The downside to this is ithat it needs
information about the line's resonator strength and rest
wavelength, the former found by aid of the latter. For ths I am so
far for my personal use depending on the list from VPfit, but any
list of similar format would of course do.<br>

Hi Jonathan,
<div><br>
</div>
<div>I think that's a fantastic idea! Are you raising your hand to
put the application in ? I'm happy to help with some of the
sections. Maybe Kelle is interested as well to join this effort.
The workload divided by three might be worth it. </div>

<div>What do you guys think?</div>

Tom's post reminded me of what I was thinking after
Kelle's post earlier today: a really good project for
someone would be to create a matplotlib-based spectral
line fitting package. Maybe this ESA opportunity would
work for that. Like many others I have my own routines
that I've written to do this, but they are neither
general enough nor user-friendly enough to be widely
usable. I think that a focused effort on this could
produce something that would be very helpful to many
people. The requirements would be (just off the top of
my head):</div>
<div class="gmail_default"
style="font-family:verdana,sans-serif">- gui interface,
for example for placement of line centers</div>
<div class="gmail_default"
style="font-family:verdana,sans-serif">- general methods
for inputting data (fits, hdf5, ascii table)</div>
<div class="gmail_default"
style="font-family:verdana,sans-serif">- robust fitting
routines that return error bars on fitted parameters</div>
<div class="gmail_default"
style="font-family:verdana,sans-serif">- a range of
possible line shape functions (e.g. gaussian, lorentz,
etc.) and continuum fitting</div>
<div class="gmail_default"

with both emission and absorption lines</div>

Hi everyone,<br>
<br>
The deadline for mentoring organizations for the ESA
Summer of Code in<br>
Space (SOCIS) 2013 is this coming Thursday.<br>
<br>
<a moz-do-not-send="true"
href="http://sophia.estec.esa.int/socis2013/"
target="_blank">http://sophia.estec.esa.int/socis2013/</a><br>
<br>
Since we were successful with the Google Summer of
Code, the Astropy<br>
project will not be participating as a whole, but if
you are leading<br>
the development of a Python package for astronomy,
and are interested<br>
in having a student work on your project, you should
consider<br>
applying! As part of this program, students are paid
4000 euros.<br>
<br>
Cheers,<br>
Tom<br>
<br>
