Hi Mark, There is also another problem with my pgflag. In previous versions I used to press d and then press , key to fiddle the amplitude scale and to set the max value and press key v to flag the data and it was doing a great job flagging the RFI. In current version I did the same but it says that...

Hi Jamie, I'm sure that it is the latest version since the new task uvfmeas is working. I downloaded a binary distribution from : ftp://ftp.atnf.csiro.au/pub/software/miriad I'm using ubontu X64. The reported version of gpcal is :Gpcal: version 1.0 03-May-2010 Please have a look at the distribution....

Hi There, I've just updated my miriad. it seems that nfbin is no longer available in the "gpcal" and while I tried this version of "gpcal", the solution is a completely different compare with the previous version of gpcal with "nfbin". The solution of newer version is t...

Hi Adam, I had the same problem. I had a 250 mJy source in the field (I had this problem with other less bright sources) which made horrible stripes in my image. There was not any problem with calibrator since the image of the calibrator was nice without any RFI or phase error. I tried to remove the...

Hi Jamie, Thanks for your answer. I've been trying to image the whole bandwith(2 GHz) using mfclean. I tried to redo imaging for 128 MHz and it seems it enhanced alot but it didnt clean one of the strong ponit sources in the field. I used CASA and the same problem appeared. I'm going to image in chu...

Hello everyone, I'm reducing CABB data at 16cm and when I try to image my source or secondary, after using mfclean to clean my image, I still can see the beam pattern on the image and no matter I chnge the number of iterations or box size in region the beam shape is visible. Is there any othet clean...

Hi Jamie, I made it right by working on the spectrum. As my bandpass and flux calibrator are 1934-638, after GPcopy the bandpass to my secondary calibrator and running gpboot, Do I need to run mfboot on my 1934 and secondary calibrator as well ? to calibrate my source do I just need to gpcopy calibr...

Hello every one, I'm currently calibrating my first calibrator which is in CABB mode in 16cm. After running mfcal and gpcal I noticed that the time-phase diagram is showing strange pattern. Also the real-imag diagram for stokes I is odd. The amplitude is steep which I think it should not be like thi...
