; NAME:
;       NORP_RDT2DATA_17G
;
; PURPOSE:
;       This procedure is for getting 17GHz data from the raw NoRP data
;
; CALLING SEQUENCE:
;       norp_rdt2data_17g,rdata,mvalid,timejo,fi,fv
;
; INPUTS:
;       rdata: structure of the raw data
;       timejo: structure array with 'time internal format'
;               that must be given by 'norp_rdt2timej'.
;
; OPTIONAL INPUT:
;       ndata: 2-elements long-integer array indicating the
;              position of data corresponding to the given timerange
;
; OUTPUTS:
;       mvalid: byte array indicating the data is valid or not.
;              e.g. if the data(123) obtained at time(123)
;                   was the calibration data mvalid(123)=0.
;                   If the data(124) was the real Sun flux mvalid(124)=1.
;       fi:  I (R+L) data array (mfreq,ndata)
;               data(0,*) is the time-sequencial array of the 1st
;               frequency which are read (indicated by 'rdfreq').
;       fv:  V (R-L) data array (mfreq,ndata)
;
; OPTIONAL OUTPUT:
;
; HISTORY:
;       programmed by T. Kosugi in 1984 May as Fortran program 
;       for old NoRP data format
;       re-programmed by H.Sekiguchi 1987 July - 1988 Dec.
;
;       1995 July,20    N,Shinox for new format NoRP data
;       95.04.19   ed.  add ATT correction for pol data ,correction data type
;                    changed intarr() to fltarr().,
;       95.09.04 Ver.2.0  M. Nishio and K. Hori
;       95.11.10 Ver.3.0  M. Nishio refernce level at 9.4GHz= amb -> zero
;  <<Caution: ambient level at 9.4GHz is incorrect. Use zero as ref. level>>
;       95.12.12 Ver.3.1  M. Nishio and K. Shibasaki (1GHz ATT 7dB -> 4.3)
;       98.09.03          sekix  & shinox   add 80GHz
;       98.11.20  K. Hori
;       1999-1-12 TY unify program for old/new NoRP data
;       1999-3-12 TY fimin,smax
;       2000-12-12 TY include fix for instrumental AMB data error in 1996
