Hi Mark, I tried it with one day from 2012 and one from from 2010, as you suggested, and yes the issue arises. Below is the output from invert #1-> mfclean -> selfcal -> invert #2 -> mfclean #2 -> restor The number of visibilities accepted in invert #2 are 2326708 vs 3760469 in invert #1. I checked ...

Thanks for the quick repsonse Mark. The synthesized beam is ~2.5 x 1.0 and ~3.4 x 1.1 arcsec, for the 2010 (6A) and 2012 data (6A + 6D), respectively. So there is slightly lower resolution in 2012. The resolution of the combined dataset is a little better than the 2012 data alone. However I don't th...

Dear Mark, Jamie et al. I have 24 days of ATCA 9GHz data for project C2028 and C2670. First 14 days is C2028 (2010). Last 10 is C2670 (2012). When I uvaver all the data, and go through the usual imaging and selfcal procedure I lose data after the selfcal step. i.e. I do uvaver, invert, mfclean, self...

Hi Mark, Andrew, et al. I can't get linmos to run without a pb correction by setting pbtype to SINGLE. That gets set after one run of linmos anyway, but we found second run of linmos will run a second pb corr on top of that. I tried unsetting pbtype, and then setting telescop to FOO (i.e. something ...

Dear Mark, Jamie, et al., I'm trying to convert a linmos output, so miriad image file, to a fits file. >fits in=mosaic.mir out=mosaic.fits op=xyout fits: Revision 1.32, 2014/09/15 04:39:01 UTC ### Fatal Error: Image too big for me to handle This is with the latest binary version for Mac OSX, so the ...

Dear gurus, I am trying to run uvsfit but am getting this error message: uvsfit: Revision 1.5, 2013/08/30 01:49:21 UTC Reading the data ... ### Fatal Error: Buffer overflow My input params are: uvsfit% inp Task: uvsfit vis = ecdfs_allepochs_17_i.5500.uv stokes = line = select = object = point spar =...

Dear Mark, Jamie, et al., I'm doing some imaging of CABB 16cm data, splitting data into 256 MHz chunks to make things easier. I'm wondering if anybody can tell me what options=mfs does in restor. I've never used that option before, but since I use mfclean and options=mfs in invert and selfcal I gues...

Okay, thanks Jamie. I'll keep that in mind for next time. I worked around it by doing an initial flagging in pgflag with options=nocal,nopol, getting most of the RFI out, then gpcal on 2333-528.2100 to generate its on solutions, and then pgflag etc. uses the gain tables in 2333-528 and no data after...

Hi Mark and Jamie, et al., I'm trying to calibrate some 16cm continuum data that has observations over a timespan > 12 hours. I do a usual mfcal, gpcal on 1934-638: mfcal vis=1934-638.2100 refant=4 interval=0.1 options=interpolate gpcal vis=1934-638.2100 refant=4 interval=0.1 options=xyvary nfbin=16...

Hi, I've making I, Q and U cubes of CABB 5.5 GHz data, across the full 2 GHz band, so that we can investigate RM synthesis techniques in measuring the rotation measure of some sources. I run invert with the folllowing (e.g. for U): vis = ecdfs_fullband_6.5500.uv map = ecdf_fullband_line10chan_6.umap...
