09:12 PM GammaLib Bug #3499: COMPTEL TS map has same values in all pixels
I checked that TS maps can be produced for all kinds of CTA analysis (unbinned, binned and stacked).
08:28 PM GammaLib Action #3501 (Closed): Implement vectorised response computation for COMPTEL
Merged into @devel@.
05:03 PM GammaLib Bug #3499: COMPTEL TS map has same values in all pixels
The DRM cache is still needed for the event-wise access.
The CTA TS map looks also good, but I have not yet done t...
04:56 PM GammaLib Action #3501 (Pull request): Implement vectorised response computation for COMPTEL
04:55 PM GammaLib Action #3501: Implement vectorised response computation for COMPTEL
Below the valgrind analysis for the transposed matrix. As expected, matrix access is no longer a bottleneck (the @GMa...
04:48 PM GammaLib Action #3501: Implement vectorised response computation for COMPTEL
Transposing the matrix in @GObservation::likelihood_poisson_binned@ and accessing it through the @GMatrixSparse::colu...
03:32 PM GammaLib Action #3501: Implement vectorised response computation for COMPTEL
Here is a valgrind analysis of the 5 standard band @ctlike@ run on viewing period 1. Obviously a significant fraction...
02:41 PM GammaLib Action #3501: Implement vectorised response computation for COMPTEL
The same holds for the TS map computation. No speed-up because the spatial parameters are fixed.
02:04 PM GammaLib Action #3501: Implement vectorised response computation for COMPTEL
There is basically no speed-up in the spectral analysis, which is normal since the spatial parameters are fixed in th...
01:29 PM GammaLib Action #3501 (In Progress): Implement vectorised response computation for COMPTEL
I implemented a vectorised response computation in @GCOMResponse::irf_ptsrc()@ making use of the characteristics of t...
