Imager #20: 161226 calibration data (e.g., MKC10001.OUT)
Imager #21: 161226 calibration data (e.g., MLC10001.OUT)

All the calibration file names are ********.OUT.  
M is the imager number, C is the filter number.  For example, 
MFC10001.OUT is Imager #15, filter number 2.
M1C22456.OUT is Imager #1, filter number 2, 2456 is f=24mm, F5.6.

Calibration equations (December 27, 2016, Kazuo Shiokawa, ISEE, Nagoya Univ.)

The CCD counts obtained by integrating sphere
  Nc = a tc ΣI(λ)T(λ)dλ + DK               ...(1)    Σ is integration
      Nc [count]     :counts at a pixel
     a [count/R/s]  :sensitivity of the optics
     tc [s]         :integration time
      I(λ)[R/nm]   :intensity of the integrating sphere 
     T(λ) [no dimension] :transmission of filter
          (normalized as T(λ0)=1 at peak transmission)
      dλ [nm]       :step of wavelength for filter calibration(=0.025nm)
      DK [count]     : dark count
 
Thus, the sensitivity of the optics is given as 
    a = ( Nc - DK ) / ( t ΣI(λ)T(λ)dλ )        ...(2)
Here we take the sensitivity A [count/R/s] as 
    A = a T(λ0)
      λ0    [nm]      : observation wavelength (e.g., 630.0nm)
      T(λ0) [no dimension]  :filter transmission at observation wavelength
          (normalized as T(λ0)=1 at peak transmission)
We store this A [count/R/s] in calibration file.  
(M1C12456.OUT, M1C10002.OUT)



In case of actual airglow observations, the output CCD count is 
  Na = a ta I(λ0) T(λ0)  +  a ta Ib dFa  + DKa      ...(3)
     Na [count]      :count at a pixel
    ta [s]          :integration time
     I(λ0)[R]      :intensity of the airflow
     Ib     [R/nm]   :intensity of background continuum
    dFa    [nm]     : equivalent bandwidth of the filter
                    dFa = ΣT(λ)dλ
          (normalized as T(λ0)=1 at peak transmission)
     DKa [count]     : dark count


To obtain Ib [R/nm], we use observation with a background filter (572.5nm).  
The CCD counts when we use the background filter is 
  Nb = ab tb Ib dFb  + DKb                           ...(4)
     Nb [count]     :count at a pixel
    ab [count/R/s] :sensitivity of the optics at the background wavelength
    tb [s]         :integration time at background observation
    dFb [nm]        : equivalent bandwidth of the background filter
   DKb [count]     : dark count at background observation


From equation (4)
  Ib = ( Nb - DKb ) / ( ab tb dFb )
      = ( Nb - DKb ) * T(λb) / ( Ab tb dFb )            ...(5)
Here   
  Ab [count/R/s] = ab T(λb)
     T(λb) [non dimension]  :filter transmission at background wavelength 
                        (572.5nm)
          (normalized as T(λ0)=1 at peak transmission)

Ab [count/R/s] is also stored as a calibration file.  
T(λb) and dFb was also determined by the calibration.  

Using Ib obtained from equation (5), the airglow intensity (λ0) [R] is obtained 
by equation (3) as 

I(λ0) = ( Na  -  a ta Ib dFa  -  DKa ) / ( a ta T(λ0) )
       = ( Na  -  A ta Ib dFa / T(λ0)   -  DKa ) / ( A ta )    ...(6)

A, T(λ0), dFa are given from the calibration file, ta is an integration time, 
Ib is given by equation (5), Dka is given from counts at the edge of the CCD.

6. Imager Attitude Parameters for Coordinate Transformation

全天画像-->緯度経度画像の変換に必要なカメラの姿勢パラメータの定義
definition of attitude parameters of airglow imagers for conversion from all-sky coordinates to glat-glong coordinates 

xm, ym:  全天画像中の天頂のピクセル位置(location of zenith in x,y pixel)
a_val: 画像直径(ピクセル)/3.14159 
       (diameter of 180-deg all-sky image in pixel / 3.14159) 
rotation: 画像の上方向と地理的な北のなす角。rotation が正の場合は、
      画像の上が真北よりも東方向に向いている。
     (angle between image top direction and geographical north direction.  
     When the image top is eastward from the north, the rotation becomes 
     positive value.)
