This file begins with a header which contains useful information about the Doppler recording equipment of the ESA radio antenna station: the Intermediate Frequency & Modem System (IFMS). A description can be found in the corres- ponding level 1b label file in the note, which describes the configuration_table. This level 1b label file has almost the same file name as this one. The only difference is that instead of 'L1A' the file name contains 'L1B'. It can be found in the corresponding subfolders under DATA/LEVEL1B/ for the data files. Further explanation of the IFMS AGC file format can be found in the MaRS/RSI/VeRa file naming convention document MEX-MRS-IGM-IS-3016, ROS-RSI-IGM-IS-3087,VEX-VRA-IGM-IS-3009 which is located under DOCUMENT/MRS_DOC, DOCUMENT/RSI_DOC, DOCUMENT/VRA_DOC respectively. For a detailed description see chapter 6 in the IFSM-OCC interface control document IFMS_OCCFTP which is located under DOCUMENT/ESA_DOC. Please note that the header format changed in May gradually. In May 2005 the IFMS3 files already have the new header whereas IFMS1 and IFMS2 still contain the old header. Since end of May 2005 all IFMS files contain the new header. Below the header section the data section starts: The 1st column contains the SampleNumber. The 2nd column contains the UTC ground received time of measurement in the format: CCYYMMDD.HHMMSS.sss . The 3rd column contains the carrier level in dBm. The 4th column contains the polarisation angle in cycles of the received signal. It gives the power splitting between RHC (Right Hand Circular) and LHC (Left Hand Circular) polarisation of the received signal. So an angle of 0.125 cycles (45 degree) would mean that power of RHC equal power of LHC. An angle of 0.25 would mean that all the power is in only one of the polarization. In normal circumstances the values in this field should be around 0 or 0.25." ^FILE = "R62ICL1L1A_AG2_152680307_01.RAW" PRODUCT_ID = "R62ICL1L1A_AG2_152680307_01.RAW" RECORD_TYPE = UNDEFINED START_TIME = 2015-09-25T04:07:22.000 STOP_TIME = 2015-09-25T05:07:12.000 END
