Re-derive analytically with the intermediate steps and motivate with pictograms the transfor-mations from geocentric right ascension and declination to topocentric right ascension anddeclination and to topocentric azimuth and elevation. Show the hour angle and the siderealtime explicitly in your drawings. Define all terms and variables.
