Thank you
Welcome!
Great tutorial ❤😂🎉
Sir I am working on STIX Quick Look Curve Data. I am looking for a background removal technique for 4-10 keV flux data. Can you suggest anything.
❤😂🎉
how would i plot data from an excel sheet for example
Read each column data from excel sheet using python and after that plot it.
Great tutorial 😂❤🎉

Loved the video! How do I make the background of the zoomed-in plot be a grid? If I do: zm.grid(True) or ax.grid(True) I only get a grid for the main plot, but not for the zoomed-in version.
Great! I will let you know...
Apply: command" zm.grid(True) ". It is working in my code. Please let me know if still the problem is not solved...
@@Astro_Jyoti Thanks, but it still does not work. "zm.grid(True)" does nothing. "ax.grid(True)" applies a grid to the main plot, but not the small one.

I'm a beginner but I know Python. From which playlist should I start learning?
This playlist will be good to start as it contains everthing : ruclips.net/p/PLqgA9FXm2K5yfJVlhf7GoZWMeD7sgQ6Z-
@@Astro_Jyoti Thank you, Sir 👍🏻 Sir, I am currently in 1st semester of my bachelor's degree in Physics. Which skills should I learn and which internships should I look for to get into IUCAA in future?
I will advise to you focus on your fundamentals and basics of subjects. Same stuff they asked in the IUCAA PhD interview. No extra internship is an eligibility criterion, Your master's thesis will be enough.
@@Astro_Jyoti Thank you, Sir 👍🏻

Helpful, thank you sir.
You are welcome
i am dealing with area histogram and i am applying multi gaussian fitting on that which gives me the three parameters, amplitude, mean value and standard deviation. but when when i convert the scale from area histogram to energy (calibration process), it does not give the correct values in energy range. how to deal this??
I think you need to adjust the energy range accordingly while fitting. Let me know if it worked out.
@@Astro_Jyoti I did it several times. But I think there is always a discrepancy left due to gaussian fitting. If you dont mind, is there any possible way thay i can show you my results so that we can discuss little bit about it?
Email me first : jyoti.prakash@iucaa.in
That's barely 1 lakh rupees lil
Ohh Really! Please send me the link.
I appreciate the information but I'm not able to even listen through because I can barely understand the accent. 😥 Thank you for your effort though.
Sorry to hear about that. you may refer to the English subtitle...Accent may vary from country to country(-_-)

Beautiful video. Will you be explaining the rest of the methods too? Also can you make a video of how to extract radial velocity curve from stellar spectra?
Thanks! Mostly people used the "Mean" stacking method. Sorry! I won't be using the rest of the methods. But you may give a try...(-_-)
@@Astro_Jyoti Thank you for the reply. Can you consider doing a video on Radial Velocity extraction?
Sure. But you need to wait enough...(-_-)
@@Astro_Jyoti of course ;)
