AI Thread Summary
The discussion focuses on the challenge of converting a Healpix file, used for sky surveys, into a traditional FITS format for easier data extraction at specific coordinates and frequencies. The original poster seeks guidance on handling the Healpix format, as they are unfamiliar with its structure compared to FITS files. Another participant expresses a related issue, wanting to convert a FITS file into a Healpix format. The conversation highlights the need for expertise in both file formats within the astronomy community. Assistance from those experienced in Healpix is requested to resolve these conversion challenges.

Not that this is really an astronomy question per se, but astronomers are most likely to know the answer.

I have a file containing a sky survey that is in healpix format, and I need to extract the data at certain longitudes and latitudes and at certain frequencies...

In a traditional fits format i could just read the corresponding rows and columns in the file, but I'm lost as of what to do with a healpix file.

If anybody with healpix experience could help, i'd appreciate it.

Hello,
I'm sorry I do not have the solution to your problem. But I have a similar problem. I wanted to know how to convert a FITS file to a Healpix file
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
