Added in R and L as a valid polarization basis to lsl.correlator.fx.

2 lines of code changed in 1 file:

• branches/lsl-1.0.x/lsl/correlator: fx.py (+2 -2)

jdowell 2014-07-29 10:21 Rev.: 1703

Fixed a version number regression in lsl.correlator.fx. 0.7 is less than 0.8.

jdowell 2014-03-11 16:41 Rev.: 1589

Various fixes in spec.c and stokes.c to deal with a problem computing the number of overlapped FFTs to run. Fixed a bug in core.c that caused the last FFT window not to make it in to the integration and the same 'overlapped FFTs' bug as spec.c. Removed the lsl.correlatore.fx.SpecMasterP function and the associated functions in spec.c. Updated the test_fx.py test suite to make sure that things are being computed correctly. This should help with addressing Ticket #51.

A few more fixes to try and get the PyFFTW stuff reliable.

jdowell 2013-12-13 14:46 Rev.: 1541

Added a new 'useWisdom' attribute to the various lsl.correlator.* modules to expose whether or not FFTW wisdom is being used. Switched everything over to FFTW_ESTIMATE.

Looks like we should only use the PyFFTW module in lsl.correlator.filterbank for complex data types.

Looks like the new PyFFTW framework in lsl.correlator.filterbank is still off.

jdowell 2013-12-11 16:41 Rev.: 1535

Looks like the new PyFFTW framework in lsl.correlator.filterbank is a little off.

Further improvements to the PyFFTW-enabled modules.

Another missing import statement...

jdowell 2013-12-10 11:22 Rev.: 1529

Fixed a few missing import statements in the updated lsl.misc.dedispersion and lsl.correlator.filterbank modules.

2 lines of code changed in 1 file:

• branches/lsl-1.0.x/lsl/correlator: filterbank.py (+2)

jdowell 2013-12-10 11:17 Rev.: 1528

Added PyFFTW wisdom support to lsl.correlator.filterbank and lsl.misc.dedispersion. Switched the varous FFTW C extensions over to floating point since the input data is at most float32 (but really integers).

190 lines of code changed in 4 files:

• branches/lsl-1.0.x/lsl/correlator: core.c (+38 -38), filterbank.py (+10 -3), spec.c (+74 -74), stokes.c (+68 -68)

jdowell 2013-12-04 15:12 Rev.: 1519

Looks like the new read_wisdom() functions in the various C extensions didn't have error checking enabled.

12 lines of code changed in 3 files:

• branches/lsl-1.0.x/lsl/correlator: core.c (+4 -2), spec.c (+4 -2), stokes.c (+4 -2)

jdowell 2013-12-04 15:06 Rev.: 1518

Worked on bring FFTW wisdom to the various lsl.correlator.fx functions. Added a new lsl.misc.wisdom module for building/update the wisdom and a new makeWisdom.py script.

62 lines of code changed in 4 files:

• branches/lsl-1.0.x/lsl/correlator: core.c (new), spec.c (+22 -3), stokes.c (+20 -1)

jdowell 2013-12-03 12:04 Rev.: 1514

Added support for PyFFTW in the lsl.correlator.filterbank module and retooled the implementation in the lsl.misc.dedispersion module.

22 lines of code changed in 2 files:

• branches/lsl-1.0.x/lsl/correlator: filterbank.py (new)

jdowell 2013-11-30 10:39 Rev.: 1510

Looks like r1461 didn't make it into the development trunk that was copied over to make LSL 1.0.x branch.

0 lines of code changed in 4 files:

• branches/lsl-1.0.x/lsl/correlator: spec.c (new), stokes.c (new)

jdowell 2013-11-22 14:46 Rev.: 1498

Created a new branch for LSL 1.0.x and incremented the version on the development trunk.

724 lines of code changed in 2 files:

• branches/lsl-1.0.x/lsl/correlator: fx.py (new 491), uvUtils.py (new 233)
