psradd question

0 votes
I have a bunch of contiguous files, each covering 5 minutes of observation, that I would like to combine and turn into a single .ar file.  I tried using:

psradd -f out.ar files*.ar

When I look at the output file with "pav -YF", it looks like the time span is only 5 minutes.  In other words, it looks like the individual archives were averaged out rather than concatenated to span the whole observing duration.  The individual sub-scans were produced using dspsr:

dspsr -E psr.par x1.fits -O file1.ar -L 10 -A

I am new to psrchive and not very familiar with this package. Any suggestions?

Thanks.

Hi Walid,

 

Since you are new to psrchive, I will recommend you use psrplot instead of pav. It's much more flexible. To get the same plot you would run 'psrplot -pY -j F out.ar'

psradd does not support any '-f' option, unless you are running some very old version which does. In any recent version you choose the name of the output file using 'psradd -o out.ar files*.ar'

Could you post the output of :

psredit -c nsubint,length,int:duration out.ar files*.ar

Cheers,

Stefan
