mapR2ObsToR3Obs_G and getObsIndex might cause error in RINEX2

[htyeim]

Rinex3ObsToR3Obs_G.cpp

If the code in Rinex2 is "P1", in mapR2ObsToR3Obs_G(), it can convert to "C1W". But in getObsIndex("P1"), it just simply convert to "C1P". So it will throw exception... Is this correct or I misunderstand the rinex file format?
