Type in the right ascension coordinates expressed in hours, minutes and seconds and declination coordinates expressed in degrees, minutes and seconds.[br][br]This is just a draft project. I haven't tested different combinations of quadrants.[br]Here is the link to the Caltech calculator:[br]https://ned.ipac.caltech.edu/forms/calculator.html[br][br]I used J2000.0 coordinates:[br]α[sub]0[/sub][sub] [/sub]= 192.8595[sup]ο[/sup],[br]δ[sub]0[/sub][sub] [/sub]= 27.1283[sup]ο[/sup],  [br]l[sub]0 [/sub]= 122.9320[sup]ο[/sup]
