The output about "pdv -t" ?

0 votes


I use "pdv -t file.fits > new.dat"  or "pdv -A file.fits > new.dat" to  output the data.

 The last four columns  stand for what ?  I,Q,U,V ? or not? Where Can I find the information?

Thank you.

Hi psrnewer,

The output of pdv will depend on the contents of your archive. You can see what state is your data in with the following command:

psredit -c state.fits

If the answer is not "Stokes", then in order to return I, Q, U and V you need to convert your data to Stokes state. If you want to keep your archive just like it is without making any changes you could run:

pdv -j 'state Stokes' -t file.fits > new.dat

Hope this helps.
