PSRCHIVE user documentation: pdv

1.0 Purpose

The Pulsar Data Viewer, pdv, is designed to display some basic archive data. Including
  • Pulse widths and mean flux density
  • Polarization summary
  • raw profile data as ascii

2.0 Usage

pdv is very simple to use, it accepts the following arguments. 
-b ibin
Select a single phase bin, from 0 to (nbin - 1) 
 -n ichan
Select a single frequency channel, from 0 to (nchan - 1) 
 -i isub
Select a single integration, from 0 to (subint - 1) 
 -r phase
Rotate the profiles by phase before printing 
 -F
Fscrunch first 
 -T
TScrunch first 
 -p
Pscrunch first 
 -C
Centre first 
 -B factor
BScrunch by this factor first 
 -x
Convert to Stokes and also print fraction polarisation 
 -y
Convert to Stokes and also print fraction linear 
 -z
Convert to Stokes and also print fraction circular 
 -Z
Convert to Stokes and also print position angle 
 -c
Print out calibrator (square wave) parameters 
 -f dcyc
Show pulse widths and mean flux density (mJy) with baseline width dcyc 
 -I
Print mean flux density 
 -R
Do not remove baseline 
 -t
Print out profiles as ASCII text 
 -A
Print out profiles as ASCII text ( with per channel headers ) 
 -S params
Print out per subint data ( -h S to list valid params ) 
 -H params
Print out the history table for the archive ( -h S to list valid params ) 
 -h arg
Print out more detailed help for program arguments. Currently lists all available options for H and S 
 -N
Print the S/N

3.0 Testing and examples

3.1 History table

To display the processing command used at each revision of the file and the centre frequencies obtained at each step 

 pdv -H ctr_freq,proc_cmd *files*

3.2 Subint parameters

To display the subint parameters from each subint, showing the tsubint and offs_sub 

 pdv -S TSUBINT,offs_sub *files*
