How to Superimpose Flux Values on an Aitoff All Sky Map?

[manjeet85]

Hi all,

I need to get an aitoff all sky flux map. I have flux given by an equation that depends on different latitudes and longitudes.

I also know how to get aitoff projection in maple 12:


My problem is that I do not know how to superimpose my flux values on this aitoff map to get an all sky map like this:

Is there any other easier way to make aitoff all sky maps?

Any help is appreciated.

Thanks
Jeremy

Hello Jeremy,

Thank you for reaching out with your question about creating an aitoff all sky map. The aitoff projection is a useful tool for visualizing data on a global scale, and there are a few different ways you can superimpose your flux values onto the map to create an all sky map like the one in the example you provided.

One option is to use a software program specifically designed for creating maps, such as IDL or Python's matplotlib library. These programs have built-in functions for creating aitoff maps and overlaying data onto them. You can input your flux values as data points with corresponding latitudes and longitudes and the program will automatically plot them onto the map.

Another option is to use a spreadsheet program like Excel or Google Sheets. You can plot your data points on a scatter plot and then use the program's chart formatting tools to change the projection to aitoff. This will allow you to see your data points plotted on a global scale.

If you are comfortable with coding, you can also use a programming language like Python or R to create your aitoff map. There are many tutorials and examples available online for how to plot data on an aitoff projection using these languages.

I hope this helps and gives you some ideas for how to create your all sky map. Best of luck with your project!
