I can easily write a script to cycle through and change the input and output file names but I'm not sure how to run AIPS each time. I have a line in the bash script which opens up AIPS but then I get stuck as I'm not sure how to enter my user ID and run uvcon and close it each time<br /><br />Any help would be great<br /><br />Thankskatenoreply@blogger.comtag:blogger.com,1999:blog-8698858162387672100.post-57363276973294033882012-08-30T01:30:37.887-05:002012-08-30T01:30:37.887-05:00Hi,

This is written in an AIPS-compatible way. It is named as HAPPY.FOR<br /><br />I have a 31DEC11 binary version of AIPS installed on MacOSX Lion. <br /><br />I have tried going through the AIPS cookbook on adding new tasks. But unlike modifying an existing task or creating a talk from one of AIPS templates, this is a slightly different situation.<br /><br />My question is how do I integrate this task into AIPS? Any help in this regard would be greatly appreciated.<br /><br />Thanks,<br />NithyaAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8698858162387672100.post-43197830729631822602012-05-31T04:23:19.404-05:002012-05-31T04:23:19.404-05:00thanksthanksAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8698858162387672100.post-38514717637722856042012-04-24T20:02:17.395-05:002012-04-24T20:02:17.395-05:00During selfcal, after running imagr, I usually run...During selfcal, after running imagr, I usually run task 'ccedt' to filter clean components and retain those defined by boxes.

My work entails me to extract the spectral flux from data cubes.I use ISPEC to do the same.To extract the spectra I wrote a procedure to call ISPEC and provide it with the BLC and TRC values(the pixel values corresponding to the sources in the image)for it to extract the spectra.But the output of ISPEC seems to give out incorrect RA and DEC values corresponding those pixels that was inputed.There seems to be a problem transforming the pixel values to their corresponding RA and DEC values.<br />Hoe does ISPEC do the pixel to co-ordinates tranformation?<br />I would be grateful if somebody could help sort this problem.Thanks in advance!Chandrahttps://www.blogger.com/profile/02067757476540518610noreply@blogger.comtag:blogger.com,1999:blog-8698858162387672100.post-17027658932490371252011-12-08T16:05:50.732-06:002011-12-08T16:05:50.732-06:00Along these lines (sort of - I'm not sure wher...Along these lines (sort of - I'm not sure where to post my question). I'm using task PCNTR to plot a contour map with intensity, polarization intensity and polarization angle files. Now I'm trying to get a grey-scale map in the background. It's working, but it makes the plot unreasonably small.

I haven't tried dowait=false option, but an ugly yet clever workaround is to hit cntr-c while imagr continues to run in the background. Log into aips again and do a "tget imagr" and "tell".<br /><br />Hope this helps!Rupalnoreply@blogger.comtag:blogger.com,1999:blog-8698858162387672100.post-47748785149824547382010-07-29T11:11:55.582-05:002010-07-29T11:11:55.582-05:00Thanks.
