SUMMARY

The discussion centers on sourcing COBE, WMAP, and PLANCK mission data for analyzing the early universe using a specific tool designed for data in latitude/longitude/"data" format. The user seeks assistance in locating suitable datasets, particularly the FIRAS CMB temperature map, which can be downloaded as a .fits file. The tool mentioned requires data to be formatted appropriately, and the user plans to utilize the Python library pyfits to extract and manipulate the data for analysis.

PREREQUISITES
  • Understanding of COBE, WMAP, and PLANCK missions and their significance in cosmology
  • Familiarity with data formats, specifically latitude/longitude/"data" format
  • Experience with .fits file format and its applications in astrophysics
  • Proficiency in Python, particularly with the pyfits library for data extraction
NEXT STEPS
  • Research how to download and manipulate .fits files using pyfits
  • Explore the FIRAS CMB temperature map and its implications for early universe studies
  • Investigate additional datasets available from COBE, WMAP, and PLANCK missions
  • Learn techniques for data clustering and pattern recognition in astrophysical datasets
USEFUL FOR

Astronomers, astrophysicists, data scientists, and researchers interested in analyzing cosmic microwave background data and the early universe.

I have a tool that assesses data in latitude/longitude/"data" format as to whether the data is clustered or if there is a pattern and to what scale.

I would like to assess some of the COBE/WMAP/PLANCK data regarding the very early universe.

I got this idea after being in lecture and an image like this came up:

https://map.gsfc.nasa.gov/media/121238/index.html

This is the all-sky picture of the infant universe created from WMAP data. It is the old temperature fluctuations. My tool can be ran over this as the data was made to be LAT/LONG/"Data" format (since they made this image).

However, I am looking at https://lambda.gsfc.nasa.gov/product/cobe/
and through the various data screens, I can't seem to find any data that fits what I am looking for.

So I am here to ask if you guys know of any data or are better versed in finding the data from the COBE/WMAP/PLANCK missions.

I think what you want is this FIRAS CMB temperature map. Download the .fits file and use pyfits to extract the data. It will take some work to massage it into the format you need.

Thanks for getting back to me on this. Sorry it took so long for me to respond, this is a bit of a side project. I'll try to massage the data from this link.
