The 'tcx' data is relatively small that uses less memory space
(Appendix A.9).
But it has no information on circular polarization, and time accuracy
is about 1 sec. To read this data,
e.g. 1998-4-20 JST 17GHz,
IDL> norh_rd_tcx,'1998-4-20',index,data CR
e.g., from 1998-4-23 JST to 4-27
IDL> norh_rd_tcx,'1998-4-23','1998-04-27',index,data CR
for 34GHz,
IDL> norh_rd_tcx,'1998-4-20',index,data,freq=34 CR
You can directly give the file name as an argument
IDL> norh_rd_tcx,file,index,data CR
To plot the data use the Solar Software standard routine utplot
IDL> utplot,index,data CR
