EPIC ICS: low resolution spectra: averaged over two heads

• if both heads are open (without foil : flag = 1) - average
• if both heads are closed ( foil or foil + grid : flag = 0[2] ) - average
• if one of the heads is open (flag = 1) - its value is taken
• if only one of the heads has flag < 3 and is closed (flag = 0/2) - its value is taken

While energy spectra plotting flag value is taken into account for correct Energy Table

Derived parameter - flag is not taken into account - so each energy channel is a mixture of open/closed moments.
