 ::The Red triangle and free circle matchup. The red mark is where the coordinates you put in are located. The green circle is a source that 2MASS found at or close to your location. If there are sources found, they will show up in rows listed under the plot.  Look at the sources returned. Is there just one within 5-10 arcsec? that's probably your match; go on to the next source (steps H - K below).
-::There is more than one source indicated because your red mark is not one particular source. You have to ask yourself - is there just one BRIGHT one within 5-10 arcsec? Is there another source from that same paper within 5-10 arcsec? If the answer to either of those questions is yes, go on to steps F - G.

 F.  Go get the images in another window from the [http://irsa.ipac.caltech.edu/applications/FinderChart/ Finder Chart]. Scroll down to find the 2MASS images. Compare the images (if provided) from the original papers. Compare the finder chart image to the images provided in the papers and/or the query results. Identify which object is the one(s) in the paper. You are going to have to choose which object you think is best. Make a note in the spreadsheet.

 H.  When you have identified the source, scroll through the listed rows below the plot and find the ''designation''. Copy this and paste it into the spreadsheet. This is 2MASS's name for your object.
-I.  Do the same thing for ra and dec. Both of these will be in decimal deg, not hours or deg. Paste both into the spreadsheet.
+I.  Do the same thing for ra and dec from the row. Both of these will be in decimal deg, not hours or deg. Paste both into the spreadsheet.
 J.  Make any comments you feel necessary. If you had a hard time deciding between 2MASS sources; No sources showing up; etc.
 K.  To do another source, scroll up to the top and click the ''Return to query page'' button. Copy and paste another set of coordinates. You will have to change the radius again.

You are going to have to enter one cell's worth of data at a time in the google doc, whereas you can highlight both ra and dec at once and paste it into the query form webpage. You will notice that Gregorio did some matching to 2MASS, but it is not updated. So we need to do each one in the area we are interested in.
