docs: // Calculate the Sun Declination in degrees based on the formula: rad2deg(asin(sin(deg2rad(obliqCorr))*sin(deg2rad(sunAppLong))))
  // obliqCorr - Obliq Corr calculated by the calcObliqCorr function
  // sunAppLong - Sun App Long calculated by the calcSunAppLong function
  // Return the sun declination slice
