AST 4723 Lab 5: IDL Tutorial Objective: The purpose of the lab this week is for you to gain experience using IDL, learing the basic commands. IDL can be quite useful for generating quality figures and manipulating arrays of data. There are a number of useful resources for learning IDL. One important source of information is the help manual that is built directly into the software. Additionally, there are a number of useful online references. Specific recommended web pages include: The IDL Astronomy User’s Library http://idlastro.gsfc.nasa.gov/ Craig Warner’s IDL Guide http://www.astro.ufl.edu/~warner/IDL5220/ R.W.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
