Hi again, I'm uncertain how exactly clean and its iterations (niters) can best be used. From my understanding, you set a cut off value and set a max iteration value(niters). The task then cleans until either the cut off is reached or the max iterations is reached. However, if the residual min, max, ...

Hi again, I'm having trouble understanding how the contours in cgdisp work, so my current entry is cgdisp in=imagefile,imagefile type=p,c slev=a,1.10991E-05 cols1=1 levs1=2,3,4 device=/xs labtyp=arcsec beamtyp=b,l,4,45,1,3 options=wedge,blacklab,mirror region='arcsec,box(-5,-5,5,5)' csize=1.75 range...

Hi again, I'm still trying to nut out this visibility problem. I've found I can use uvaver to condense my observations and then fits to output the uv data, the results are shown in the attached snip of my python code loading the table. I wondering what the DATA column refers to? I need u[m], v[m], R...

Makes sense, thanks

And the centre of field is the RA and DEC the telescope was pointed at?

Hi again, Quick question, more of a confirmation. I'm zooming in to my region of interest in cgdisp using the box method, I'm looking at a protoplanetary disk so it's very small. The region documentation on miriad says for the arcsec option "the coordinates are in arcseconds, relative to the re...

Thanks for the help ,cgcurs is what I was looking for

Hi all, I'm experimenting with uvamp and want to centre my source for the task. From previous questions I've asked I know I have to correct for the primary beam attenuation and then measure the source offset with impos. However, I think I may be missing some key inputs. I'm currently following (my i...

Hi all, I'm attempting to make a visibility plot (example attached) for my target. I know uvamp can be used for this, but I was hoping to play around with the data myself (ie different bins, chi squared analysis) in python and need it in a data format with u(lamda),v(lamda),real(jy),imaginary(jy),w(...

Hi, From my previous post I'm attempting to measure the flux of my target with uvfit. Upon the previous suggestion to implement: uvfit vis=myvis line=chan,200,1,10,10 object=point I receive the following errors: uvfit: Revision 1.10, 2013/08/30 01:49:21 UTC Reading the data ... Applying bandpass cor...

Thanks for the suggestions.
