Oscillations in 1934 spectrum after bandpass cal

Hi All,

There is the third set of plots (sorry, phpBB wouldn't let me post more than 3 at a time).

Real data:

Hi All,

Yadda, yadda, yadda, final set of plots.

The main item of interest here is that antenna 6 baselines show very little ripple in the simulated data. The real data has a bit of ripple - this might be due to poor bandpass calibration as a result of ripple in the shorter baselines.

Cheers,

Emil.

I already said it in an email, but I thought I'd acknowledge it here too - great stuff Emil! Thanks for taking the time to look into this for me! For the moment it is just good to have an idea what is going on, and that it is to some extent unavoidable using the simplest approach to getting a bandpass cal with Miriad.
