Hi, I've been using convol to try to convolve mosaics that I've been making with CABB data at 8MHz intervals to a uniform resolution throughout the 16cm band. I have noticed that on the convol documentation though, it says "WARNING: Convol does not do a very good job with masked images." W...

Cheers Mark - much appreciated!

OK - thanks Mark!

Just wondering - are there any known problems with 'uvfstats' handling large datasets? I tried to use it on a uv data file for a large mosaic, and it's spitting out negative numbers for the flagged percentage like -8% and other strange things. I know for a fact that the flagged percentage is more li...

*Sigh*. Scratch that - it's a PEBKAC issue. The laptop I'm using hadn't had Miriad updated in the last year, and nfbin didn't exist back then. Stoooopid me...

I'm running gpcal on a 1-3GHz chunk of data, using nfbin=16 to try to split the band up for the cal. However, I keep getting the following warning: "### Warning: KeyFin: Parameter nfbin not used or not exhausted" Could anyone help me out on what this means? It sounds to me like it hasn't a...

OK - thanks Mark. I'll take a look at it.

Cheers,

Craig.

Hi Guys, Craig Anderson here from Sydney Uni. I've been trying to stitch together some CABB spectral cubes with linmos, and it's falling over for reasons I don't understand. The files I want to mosaic are four stokes Q cubes (one for each pointing in a sub-mosaic I'm working on), spanning a 256MHz f...

Quick question - I've accidentally flagged almost an entire dataset which I'd like to undo. I was going to simply unflag the entire dataset using UVFLAG with the flagval set to 'unflag', and then just run my reduction script again. However, I then realised that when I ATLODed the data into MIRIAD, I...
