88m28-60m00-cplxt-apl-60w08

The sensor energy range coverage, 88m28-60m00, is explained as follows:

HEEA is covering the high end of the energy range (88 down to 28) and LEEA is covering the low end (60 down to 00).
Both sensors are in Medium Angular Resolution (MAR) mode, signified here by the 'm'. Other possibilities are Low Angular Resolution ('l') and High Angular Resolution ('h').
See energy levels table (approximate) to intepret energy range

The DPU is generating the datasets 'cplxt', these and all other possible datasets are described by the following table:

c
CORE includes moments
p
PAD pitch angle data
l
LER reduced resolution low energy data
r
3DR reduced /8 resolution 3D data from LEEA and HEEA
s
3DR reduced /8 resolution 3D data from LEEA only
t
3DR reduced /8 resolution 3D data from HEEA only
x
3DX1 reduced by variable degree resolution 3D data, one sensor only
y
3DX2 second 3DX in same spin
f
3DF full resolution 3D data from HEEA and LEEA

The 3DX data selection, here 'apl', is described as follows:

a  all basic segments (else t for 2 basic segments; cartwheel slice)
p  adds together pairs of anodes (else e for adding pairs of energy bins or n for no summing)
l  data is from LEEA (else h if data is from HEEA)

'60w08' is 3DX 'windowing' information: it means that the 3DX data contains only a subset of the energy range measured by LEEA; in this case energies between level 08 and level 00 are discarded

NOTE about commanding from March 2008 onwards: when PAD_PATCH_1 has been uplinked, all PAD zones will be filled with data from the LEEA sensor only. This ends when the patch is killed.
