Conversion of ascii file to fits format #27

Closed praana closed 3 years ago

praana commented 3 years ago

Hi, I am Pranav LImaye, a bachelors project currently doing a project under Prof Yashwant Gupta at NCRA. I have taken some data from the GMRT and analysed it using gptool. I now need to convert the .gpt files from gptool into .psrfits file to verify the pulse profile shape I am getting by using psrchive. How can I proceed with this conversion?

Clear Skies, Pranav

pinta runs gptool as part of its processing. You can pass the gptool.in file you created to pinta and pinta will create a Timer archive. The timer archive can be directly used for further processing. If you really want a psrfits file, you can convert the pinta output using pam or psrconv command.

Have you installed pinta? If you have, you can find detailed usage instructions in this user guide: https://docs.google.com/document/d/13-ZWHLpGfalQ6ogbs1YSyMZjSy9gi6aFOvyQ8YYzEz8/edit?usp=sharing

Hi, I dont have pinta installed on my system but I can access the tapti server of gmrt. I will have to ask my guide to get permissions for sourcing the pinta package.

When I analyse data using gptool I get the output pulse profile file as "profile_filtered.gpt". What is the extension of the timer archive file that pinta produces?

For running gptool, I source /Data/astrosoft/astrosoft.sh and this works. I already have the .gpt files ready with me. Can I use pinta commands on them directly to convert them into timer archive files?

I tried converting the .gpt files into fits format using an online python package called "YOUR'. However, when I run psredit on this fits file I have created, the nsubint parameter is zero which effectively tells me that the pulse profile is not phase folded. Can I workout some way out of this error?

Clear Skies, Pranav

The profile archive produced by pinta has the extension of "fits".

To convert the gptool filtered file directly to archive, do the following.

Note that by filtered gpt file I don't mean the ASCII profile you mentioned. I mean the filtered data file with the name .gpt

@praana Is your problem resolved? If yes, I will close this issue.
