Just trying to work out how serious this is in terms of reprocessing large volumes of data for the MeerTime TPA. Can anyone say if this only affects in the frequency direction or might the delays also change with time - e.g. is it possible that different subints will have different offsets. Obviously if there is something that changes from pulse-to-pulse in the single-pulse data then it is more serious than if it's just that the dedispersion is wonky +/- 1 bin. (though probably we should reprocess...

So the FrontendCorrection is important if anyone wants to calibrate data using the python interface. We use it in the meertime singlepulse pipeline, but really I think it is widely needed. However, I think the most important thing is to be able to call the calibrate(Archive) method, as this is what actually applies the calibration. The python interface is a bit of a mess as it is developed piecemeal, so for sure I have no objection to just removing functions that return a Jones object. Probably someone...

remove_chan crashes thinking there are zero subints and changes channel number before loading data

I have made the committed the change in d2c905bef6e72c40be00d84a3f9e630f371b33d2. It fixes the bug in the python code, and nothing amazingly bad seemes to have happened...

I haven't tried it, but I guess I could - maybe I will have a look tomorrow. But yeah - my worry is that it will introduce some other bug...

Hmmm... the thing is that I have these defined in my config.h for epsic... so it's like it is getting the wrong config file somehow. /* define if the compiler finds best partial specialization */ #define HAVE_BEST_PARTIAL_SPECIALIZATION /**/ /* define if partial specialization accepts default template arg */ #define HAVE_DEFAULT_PARTIAL_SPECIALIZATION /**/ EDIT - ah sorry I think I misunderstood the logic - these have to not be defined for it to work I think.
