Upon visiting the MAST Portal, the first step is to change the collection of data we are searching in from the Context menu (Item #1) at the top left. |

From the Context drop-down menu, select MAST Catalogs, then, in the Mission drop-down menu that appears (Item #1), select TESS Input for the TIC. |

We are now ready to do a target search by entering text into the Search Box (Item #1). The Search Box uses a name resolver that accepts a wide range of text values, including any name that is resolvable by NED or Simbad, any catalog entry from the Kepler Input Catalog (e.g., "KIC nnnn"), the K2 EPIC Catalog (e.g., "EPIC nnnn"), and the TESS Input Catalog (e.g., "TIC nnnn"), as well as some special areas of the sky, such as "GOODS-N", "GOODS-S", "HUDF" for the Hubble Ultra Deep Field, etc. In this example, we'll do a search centered on the exoplanet host star HD 209458. |

We now see the results of our search. First, note that the default search radius is often assigned to be a 0.2 degree radius (Item #1). Exceptions are for any objects resolved by external services (like NED) that have object radii defined for them, e.g., extended objects like galaxies or clusters. These can always be changed by specifying your search radius (see the Show Examples link below the search box for examples). |

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). |
