This tutorial will show you how to do a search on a single target, based on a target name, within the TESS Input Catalog in the MAST Portal. Specifically, we will do a search centered on the exoplanet host star HD 209458.
The search results area has three main panels, on the left is the Filters panel (Item #2), where you can select subsets of your returned rows by filtering column values. In the middle is the Search Results Grid (Item #3), which contains the table of results itself (hint: columns can be sorted by clicking on the headers). On the right is the AstroViewer (Item #4), which is a 3D sky map that will overplot the footprints of observations or catalog objects from your search results, and offers a wide range of background images from surveys that span the electromagnetic sepctrum from X-rays to the radio. We can see all the TIC sources in our 0.2 degree search radius quite clearly.
We'll do a quick filter to demonstrate how to select subsets. In the Filters panel on the left (Item #1), we'll scroll down to the Luminosity Class From RPM subpanel, and check the box to only select those targets identifed as dwarfs by the reduced proper motion diagram. Note: you can use the Edit Filters... link at the top of the Filters panel to add or remove any columns from the Filters panel, not every column will show up by default in the Filters panel. You can see in the AstroView the results of selecting only these targets (Item #2).
