Modules for calculations of attributes pertaining to stellar objects Functions: -Small_Angle_Approximation_Calculation_Prompt() : Begins a prompt to perform small angle approximation calculation with user input via console. Prints the result. -Find_Theta_Arcseconds(actual_size_lyr, distance_lyr) : Find arcseconds in degrees given the size of the stellar object in light years and the distance to the stellar object in light years -Find_Distance_Light_Years(angular_size_theta, actual_size_lyr) : Find the distance in light years to a stellar object given its angular size in degrees and size -Find_Actual_Size_Light_Years(angular_size_theta, distance_lyr) : Find the size of a stellar object given its angular size in degrees and distance in light years -Convert_Parsec_to_Light_year(parsec) : Converts parallax seconds (parsec) to light years -Convert_Light_Year_to_Parsec(light_year) : Converts light years to parallax seconds (parsec) -Find_Parsec(arcsec) : Converts arcseconds (arcsec) to parallax seconds (parsec) -Find_Parsec(arcminute) : Converts arcminutes to parallax seconds (parsec)
