Initialization Error Plot
Plot of pointing errors across the sky for a given two star initialization of an altazimuth telescope
Pointing error all sky plots for altazimuth telescope initializations using stars separated by 6, 22, 38 and 81 degrees.
Green = no additional error beyond the initialization error. Red = twice the initilization error.
North is pointing up, south is pointing down.
Stars for plot 1: Deneb and Vega; for plot 2: Deneb and Sadr (Gamma Cygni); for plot 3: Deneb and Altair; for plot 4: Deneb and Fomalhaut.
