X-ray energy
FOURC> getE

FOURC> wh_gap
FOURC> mv gap [x mm]
_flg_gap_: 0,1,2
(0: no gap control,
1: gap control with special harmonics,
2: gap automatically controlled using suitable harmonics)
In the case of _flg_gap_=2 ,
- 3rd harmonic: E < 6.58keV
- 5th harmonic: 6.58keV <= E < 9.2keV
- 7th harmonic: 9.2keV <= E < 12keV
- 9th harmonic: 12keV <= E < 19keV
