Background/general reference

Light beyond the visible

There are a LOT of resources available all over the web on this, so just a few links listed here.

Central wavelengths and zero points

A reference page for bands frequently used in NITARP.

Units

Literature searching

How can you find out what scientists already know about a particular astronomy topic or object? Literature searching is an essential part of doing scientific research!

Mosaics

Typically objects or regions in space we want to study are too large for the telescope to capture in a single image or frame, so the telescope has to take many frames which are combined using software into a single image or what is commonly called a mosaic (or sometimes a map).

Resolution

Resolution matters!

Diffraction

Diffraction matters! The 'rings' you see around some Spitzer sources aren't the dust rings around those sources!

Confusion

Depending on where you are looking and what wavelength you are using and specifically what you are doing, confusion can matter!

Infrared Background

Depending on where you are looking and what wavelength you are using and specifically what you are doing, the IR background can matter!

Photometry

A discussion of what photometry is and why you would want to do it. Includes where to find already-reduced Spitzer photometry. Also see Aperture photometry using APT.

Units

If you've done photometry before and expect to do it the same way here, BE CAREFUL because IT WILL NOT WORK. The units of Spitzer images can be tricky. This page has a lot of information about these units and how to convert them into more familiar units.

Color-Magnitude and Color-Color plots

A general discussion of color-magnitude and color-color plots.

SED plots

A general discussion of spectral energy distribution (SED) plots.

Telescopes

need better title, sorting
