| version X=1:
|               fixed stemp and l1a_mode to be meet MMS CDF guidelines
|               added flag parameter (same as L2pre flag parameter)
|               Added etemp parameter.
|               Added rate, hirange
|               Use NaN FILLVALL for stemp and etemp
|               Reference temperatures are used at all times to determine gains.
|               Non-linearity correction is applied to high rage DFG data.
