Energy Ranges

The energy ranges over which the TIMAS key parameters are calculated are mode dependent.

The instrumental energy range is subject to change a few times per orbit.
The key parameter Energy_Range_ID indicates which of the 3 instrumental energy ranges is currently active. Each instrumental energy range further divided into 3 Key Parameter (KP) energy channels (low – medium – and high). The table below gives the full energy range and limits of the thee KP energy ranges. 


Energy_Range_ID=0: (Full instrumental energy range)

	Full range (0.015 - 33.3 keV/e)
	low  KP channel (0.015 - 0.37 keV/e)
	mid  KP channel (0.37  - 3.3  keV/e)
	high KP channel (3.3   - 33.3 keV/e)"


Energy_Range_ID=1:  (Reduced instrumental energy range)

	Full range (0.015 - 22.45 keV/e)
	low  KP  channel (0.015 - 0.37  keV/e)
	mid  KP  channel (0.37  - 3.3   keV/e)
	high KP  channel (3.3   - 22.45 keV/e)


Energy_Range_ID=2: (Low instrumental energy range)

	Full range (0.015 - 2.18 keV/e)
	low  KP channel (0.015 - 0.11 keV/e)
	mid  KP channel (0.11  - 0.37 keV/e)
	high KP channel (0.37  - 2.18 keV/e)
