Hi Tom,

   where I can find the s2plot-python repository? it isn't in your public repositories at github.

   thanks in advance.

Hi,
 
I have made a few changes to the s2plot python extension as listed in the

Hi folks,

 

     is there some easier way of draw a spherical grid representing the spherical coordinates than doing it by hand?

     I mean a grid like in this plot http://astronomy.swin.edu.au/s2plot/index.php?title=S2PLOT:Gallery#6dF_Galaxy_Survey.

  

     cheers,

Mario.-

Hi Mario,

I have some code that I'm happy to share which does the spherical grids.  If you can please bear with me for a day or two, I'll put it somewhere obvious on the main s2plot page.

I'm always interested to hear about/see samples of how people are using s2plot to support their research.

Regards

Chris

hi mario,

I was waiting for a go ahead before uploading it, but given your message I have stuck it on github now.

Let me know of problems.

  Thanks, Tom! It works great!

  I just had to replace the line #52 in file setup.py: 

     dylibExt = '.so'

  by

 

     dylibExt = '.a'

    

  I don't have the shared library libs2plot.so and I don't know how to build it.

Hi Mario,

I didn't realise that the Python link would work with archives (.a) as opposed to shareable objects (.so) but thinking about it, it actually builds a separate shareable object that Python can load dynamically (when you import) so it makes sense. I should have a think as to whether it would not be preferable to make the .so to .a change permanent. You only get the libs2plot.so if you set the environment variable S2SHARED to yes when installing the C library. By the sound of it, you didn't,

Tom

Hi Tom,

   

    you are right! I had set the environment variable S2SHARED to no in the bashrc file, and I forgot it when I have built the python extensions.

    

    thanks again.

Mario.-

Hi Mario,

I've now put some sample code online.  You can access this from the link on the main S2PLOT a page:

http://astronomy.swin.edu.au/s2plot/index.php?title=S2PLOT

Look for "How to create and display spherical coordinate grids"

Please let me know if it does not work for you.  

It is C code, so I'll have to leave it to you to convert to other languages, as required.

Regards

Chris

[Mario Agustin Sgro]

Hi Chris!

    excellent! It works perfectly. C is my official language :P. Thank you very much!

    Now, I'm tying to make some funny plots showing the geometrical features of a galaxy catalog.

    

  Regards, 

  Mario.-
