Matlab Map Projection Plot: How to Plot Supernovae Coordinates on a Hammer Plot

[birdhen]

Hi there,

I am trying to plot the coordinates of Supernovae onto what I think is known as a hammer plot i.e a 2D plot representing the surface of a sphere. I have no idea how to do this, and have been searching the internet to no avail. Can anyone offer any advice ? I only have a basic knowledge of Matlab.

Thank you.

Unfortunately, I've never heard of a hammer plot, and a search for it (even in quotes, which looks for exactly that phrase) turns up nothing of relevance (though it does turn up your post, and a link to the Hebrew Hammer, which I thought was a hilarious movie).

Perhaps you can make something work with MATLAB's polar plot function? You'd probably have to figure out how to plot lines for appropriate lobes (like a one-piece orange skin) but you can probably work something out:

Hello,

Thank you for reaching out for assistance with plotting Supernovae coordinates on a Hammer plot in Matlab. I am happy to provide some guidance for you.

To begin, you will need to have the coordinates of the Supernovae in a format that can be read by Matlab. This could be in the form of a text file, Excel spreadsheet, or other data file. Once you have your coordinates, you can use the "plot" function in Matlab to create a scatter plot of the points on the Hammer projection.

To ensure that your plot is properly scaled and centered, you may need to use the "axis" function to set the limits and center of your plot. You can also use the "title" and "xlabel" and "ylabel" functions to add labels to your plot.

If you are not familiar with the Hammer projection, you may want to do some research on the projection and its properties before attempting to plot your data. This will help you understand how the coordinates will be represented on the plot.

I hope this helps get you started on plotting your Supernovae coordinates on a Hammer plot in Matlab. If you have any further questions, please don't hesitate to ask. Good luck!
