Observed time so far in 2024
- Total time of each institute is calculated by the following
    [All observation time in 2024] = [Observed time so far] + [Remaining time in the future]
    [Remaining time in the future] = [Clear sky fraction] x [Remaining night time (Sun alt. < -10°)]
    
    [GB observation time in 2024] = [Observed GB time so far] + [Remaining GB time in the future]
    [Remaining GB time in the future] = [Clear sky fraction] x [Remaining GB night time (Sun alt. < -10° & GB alt. > 22°)]
    
    [Non-GB observation time in 2024] = [All observation time in 2024] - [GB observation time in 2024]
    
    [OU, NASA, ABC time in 2024] = 0.24 x [Non-GB observation time in 2024]
    [SAAO time in 2024] = 0.28 x [Non-GB observation time in 2024]
    
- ALLSKY time is equally distributed to each institute
- ToO time is distributed to each institute based on input of observer of each date
- Clear sky fraction of (0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5) is assumed for (Jan, ..., Dec) in the calculation of the remaining observation time
