John Krist modified ticket #14
prop_fit_zernikes and prop_zernikes not working in Python 3.13.2
-
They changed the behavior of the exec() function in Python 3.13. Variables created using it were visible within the calling routine's space, but now a local dict has to be passed. Made fixes to prop_fit_zernikes, prop_noll_zernikes, prop_zernikes. Posted on Sourceforge as PROPER v3.3.3 for Python.

cylindrical lens kind request
-
Requires major changes, beyond resources available.
-
Adding a cylindical lens to PROPER would require signficant changes to handle different samplings in each axis, along with separate propagations for each orthogonal component (needed because the focus is at different distances along the optical axis for such a lens). Given that this has not be requested by anyone else, and it is not needed for my own work, I cannot devote resources to make such a major rewrite. Sorry.

Hello, can you please add cylindrical lens to the PROPER (Matlab) software. Thank you

In Python, dm_prop works the same whether FIT=TRUE or FIT=FALSE

The flag options have been fixed in v3.1.5.

Okay. I misread your message. Looking through the codes, the line should read: if ( "FIT" in kwargs and kwargs["FIT"] ): Such checks are handled correctly nearly everywhere else. I found only a couple more such errors and will have my Python programmer fix them next week. In the meantime, unless a flag is True, don't explicitly provide it. John

Hello John, I agree with what you just stated. Now try proper.prop_dm( wfo, dm, 23.5, 23.5, 0.001, FIT=False ) and you will find that it behaves exactly the same way as proper.prop_dm( wfo, dm, 23.5, 23.5, 0.001, FIT=True ) Kind regards, Marcos

Hi Marcos, The code is operating correctly. If I insert messages into the prop_dm.py code like so: if "FIT" in kwargs: print( "fitting DM" ) x = (np.arange(5, dtype = np.float64) - 2) * dx_dm (blah, blah, blah) (dm_z_commanded, dms) = proper.prop_fit_dm(dm_z, inf_kernel else: print( "NOT fitting DM" ) dm_z_commanded = dm_z then I get the following results when executing the following commands using python3: proper.prop_dm( wfo, dm, 23.5, 23.5, 0.001 ) NOT fitting DM proper.prop_dm( wfo, dm, 23.5,...

Hi Gilles, Thanks for pointing out the bug. It has been fixed and new versions of the Python code have been uploaded to Sourceforge. Regards, John

Dear PROPER developper, I think there are IDL->Python translation errors in 'prop_zernikes.py'. In particular, for eps != 0, the bitwise operator ^ is used instead of the power ** (see line 181 to 219). Best regards and thank you for PROPER, Gilles Orban de Xivry

Thank you for the above suggestion. I was able to get Proper installed into a conda environment. On a different note, I have a code suggestion for you regarding Proper. This is something I have run into trying to get proper to run prescriptions that I have defined elsewhere. For various reasons, I am running the code from a remote directory relative to where the prescriptions are stored. When I try to then run proper, I need to specify the relative location of the perscription to the prop_run.py...
