Re: kvis recently started crashing
Hi Steve, I'm running on Mojave and it has been working fine for me. Maybe it is an X server issue? I have XQuartz 2.7.11 Cheers, Mark ares$ kvis Environment variable KARMABASE not found Error statting "/usr/local/karma-1.7.20/x86_64_Darwin" (compiled in) No such file or directory Defaulti...

Re: rmclean task problem
Hi Rami, I'm no expert on rmclean, having never run it myself, but looking at the code the error message indicates that the cube has too many spectral channels (or it needs reordering to get the channel axis first). The maximum is 2048. Also, the help says freq needs to be a text file with all the f...

Re: Rotation measurment problem
Hi Rami, I think what may have happened is that you forgot to specify axes=1,2 in regrid, which means it regridded all axes including the frequency one. This means all images have the same frequency in the header now and imrm doesn't like that. So try again and make sure the first two axes are the s...

Re: Rotation measurment problem
Hi Rami, welcome to the forum! I've had a look at the code and there is indeed a problem at that line. I've fixed that and a new version will be built tonight. Depending on how you update Miriad, you can either do a mirsync tomorrow, or wait till Friday for a new tar file download. However, you will...

Re: Converting Miriad data into MeasurementSet form
Hi Nick, there are a few issues: * it is best to run uvsplit on the output of uvgen before conversion, this removes the 'wide' channels that are not handled well downstream * you have 128 antennas, this is more than the standard miriad can handle (MAXANT=64), importmiriad in casa has the same limita...

Re: Converting Miriad data into MeasurementSet form
Hi Nick,
I managed to reproduce the uvgen->importmiriad failure and will have a look at it today. The fits route worked for me, but I don't have your antenna file.
Can you send me the phase1.ant file so I can try this?
Cheers,
Mark

Re: cclean, pmosmem
Hi Stephen, I think your suggestion of pmosmem is good - I just tried it on a single field and it works fine. No need to use multiple pointings if you don't need them to cover the object. The other thing you can try is a new feature in cclean (borrowed from wsclean) to do a second clean to a deeper ...

Re: Any primary beam correction after MOSMEM/PMOSMEM?
Hi Ryan, I did a few tests and I think the effect you see might be a mosmem 'feature' that produces a small offset at the level of the noise. I don't see the same effect with mossdi. If I run mosmem on a mosaic with just noise I get an image like the one below. I think it shows something very simila...

Re: Any primary beam correction after MOSMEM/PMOSMEM?
Hi Ryan, Yes, mosmem (and pmosmem) normally correct for the primary beam. In fact invert should already have done this when making the dirty images. But it uses the same method as linmos with options=taper, which means the images have the correct flux between pointings, but are uncorrected at the ed...

Re: Excluding antennae from miriad data reductioin
You must be trying to use miriad from the command line rather than the miriad shell.
On the command line you can either 'escape' brackets with \ or place the whole keyword=value in quotes:
% uvplt vis=data.uv "select=-ant(6)"
