A tool for uGMRT primary beam correction

Finalflash

Finalflash is a tool for correcting radio interferometric images using the uGMRT primary beam model. Inspired by Vegeta’s ultimate attack in Dragon Ball Z, this tool provides accurate corrections for uGMRT FITS images.

Citation

If Finalflash saves your analysis from the chaos of uncorrected primary beams and handling CASA tasks, give it a little love in your acknowledgements! Add this line in the acknowledgement section:

"Primary beam corrections were performed using Finalflash, hosted at https://github.com/arpan-52/Finalflash."

Until it makes its debut on ASCL or I finally write my holography paper, your acknowledgement would be super appreciated. As some random user in the internet mentioned: "Science without ethics is like a spaceship without fuel—sure, it looks good, but it’s going nowhere."
