# Parameters required for four types of parameters related to electric circuits are included.
# Parameters of (2), (3), (4) are used to in creation of ONC L2b images.
#
#   (1)  a/d conversion adu  [e-/count]  (Table A1 of [2])
# 
#   (2)  Bias
#          ONC-T (equation 3.5 and 3.6 in [2])
#            I_bias [count/s]
#               =   ( b0 + b1 * T_(CCD,T) + b2 * T_(ELE,T) )
#                  *( b3 + b4 * T_AE )
# 
#          ONC-W1, ONC-W2 (equation 5.1 in [2])
#            I_bias [count/s]
#               =   ( c0 + c1 * T_AE + c2 * T_AE**2 ) * T_(CCD,W1 or W2)
#                 + ( c3 + c4 * T_AE + c5 * T_AE**2 )
# 
#        Note: the value -999 means "not applicable".
#
#   (3)  Dark signal (equation 3.7 in [2])
#            I_dark [count/s] = exp( d0 + d1 * T_(CCD,T or W1 or W2) )
# 
#        Note: Values for W1 and W2 are filled tentatively with values for T.
# 
#   (4)  CCD vertical transfer time per pixel
#            t_vct_pixel [s/pixel]
