These numbers are legitimate estimates of the telescope tracking errors The intensity distributions really look like the telescope images!!!!! if Guiding == 1: #GOOD SET FOR E=.18 m_dec = -0.0042 #Slope of tracking error in DEC (arcsec/sec) m_ra = 0.0020 #Slope of tracking error in RA (arcsec/sec) A_osc = 2.000 #Amplitude of oscillation of RA (arcsec) f_osc = 0.00810 #Frequency of oscillation of RA (1/sec) eps_see = 4.20 #Seeing disc in pixels (arcsec) I_o = 10.00 #Maximum intensity of star (ADU) t_exp = 1800. #Exposure time in seconds (seconds) Num_ts = 84. #Number of times telescope was offset RA_DEC_Ratio = 14 elif Guiding == 0: #GOOD SET FOR E=0.06 m_dec = -0.0042 #Slope of tracking error in DEC (arcsec/sec) m_ra = 0.0020 #Slope of tracking error in RA (arcsec/sec) f_osc = 0.00810 #Frequency of oscillation of RA (1/sec) A_osc = 2.1004 #Amplitude of oscillation of RA (arcsec) eps_see = 6.20 #Seeing disc in pixels (arcsec) I_o = 10.00 #Maximum intensity of star (ADU) t_exp = 1800. #Exposure time in seconds (seconds) Num_ts = 1. #Number of times telescope was offset RA_DEC_Ratio = 1
