Conversion from galactic coordinates to image coordinates

[physical101]

Dear All

I was wondering if anyone knew of a tool/library in Matlab that would enable me to convert from galactic to physical image coordinates.

I can read the header file etc of a fits file but I am at a bit of a loss as how to use this information to get real image coordinates.

Cheers

Dear Duane,

Thank you for your question. There are several tools and libraries available in Matlab that can help you convert from galactic to physical image coordinates. One option is the Astronomy Toolbox for Matlab, which includes functions for coordinate transformations and image manipulation. Another option is the FITSIO library, which allows you to read and write FITS files and extract information from the header.

To use the header information to get real image coordinates, you can use the WCS (World Coordinate System) keywords in the FITS header. These keywords provide information about the coordinate system used in the image, including the transformation between pixel coordinates and physical coordinates. You can use the functions in the Astronomy Toolbox or the FITSIO library to extract this information and apply it to your data.

I hope this helps. Good luck with your research!
