# Developing System : R 4.1.1 (2021) #
# #
# Short Description : #
# #
# 'TreatDobsonData.R' contains functions for the reading, writing #
# and processing of total ozone values of Dobson measurements from #
# and to different data formats: #
# #
# - 'AEyyyymmdd.iii'-files (single day file) #
# #
# - 'AXyyyymmdd.iii'-files (extended output information) #
# #
# - 'DAYOZON_yyyy.iii' (daily values output file (1-line format)) #
# - 'DAYOZyyN.iii' (daily values output file (4-line format)) #
# #
# - 'HDOZON_yyyy.iii' (halfday values (1-line format)) #
# #
# #
# List of functions: #
# #
# - GetUmkTotoz #
# - ManuFlagAE #
# - ReadDobsonAE #
# - ReadDobsonDD #
# - ReadDobsonLV #
# - ReadDobsonUM #
# - ReadLuxfile #
# - ReduceAE #
# - SetFlagsAE #
# - TreatDobsonUM #
# - UpdateLuxfile #
# - WriteLuxfile #
# - WriteDobsonAE #
# - WriteDobsonAD #
# - WriteDobsonDD #
# - WriteDobsonCX #
# - WriteDobUmkpre #
# - WriteDayStatis #
# - WriteDayoz #
# - WriteHalfDayStatis #
# #
# #
# Former name of file was 'TreatDobsonAE.R' (created 29.07.2009) #
# #
# #
# Modification history: #
# #
# - 23.02.2017 by Herbert Schill: #
# #
# - remove bugs in 'ManuFlagAE' (proper indexing of flags) #
# #
# #
# - 26.03.2017 by Herbert Schill: #
# #
# - adapt 'ReadDobsonLV' to recent D-file data contents #
# #
# #
# - 21.10.2017 by Herbert Schill: #
# #
# - 'print'-commands replaced by 'cat' in all procedures #
# #
# #
# - 06.12.2017 by Herbert Schill: #
# #
# - add functions 'GetUmkTotoz', 'ReadLuxfile', 'UpdateLuxfile' #
# 'WriteLuxfile', 'TreatDobsonUM' and 'WriteDobsonCX' #
# #
# - remove bug in 'ReadDobsonLV': proper last line control and #
# more detailed error messages #
# #
# #
# - 12.12.2017 by Herbert Schill: #
# #
# - remove bug in 'UpdateLuxfile' (cdate) #
# - allow 'Cx' header choice in 'WriteDobsonCX' #
# #
# #
# - 19.12.2017 by Herbert Schill: #
# #
# - 'ReduceAE': measurements with an airmass bigger than #
# maxAirmass resp. a sun intensity lower than minSun are also #
# filtered #
# #
# #
# - 28.12.2017 by Herbert Schill: #
# #
# - 'WriteDobsonAE': if 'AX'-output format is required, the #
# R- and Ozone-values are written with higher precicion #
# #
# #
# - 20.01.2018 by Herbert Schill: #
# #
# - 'TreatDobsonUM': proper test on minimal and maximal sunhei in #
# range [0°..MinSunhei°], MinSunhei hardcoded #
# #
# #
# - 21.01.2018 by Herbert Schill: #
# #
# - Add function 'WriteDobUmkpre' #
# #
# #
# - 24.01.2018 by Herbert Schill: #
# #
# - 'TreatDobsonUM': remove bug in proper test on minimal and #
# maximal sunhei in range [0°..20°] #
# #
# #
# - 27.01.2018 by Herbert Schill: #
# #
# - 'TreatDobsonUM': allow filtering of measurements with #
# StaDevR>LimitSDevR #
# #
# - 'TreatDobsonUM': reorganising error message structure #
# #
# - 'ReadDobsonUM': include HV-values in data-list #
# #
# #
# - 14.02.2018 by Herbert Schill: #
# #
# - 'WriteDobsonAE': R-values are written with 2-digit precicion #
# #
# #
# - 09.03.2018 by Herbert Schill: #
# #
# - 'WriteDobsonAE': check on maximal SDev-value of 99.99 #
# #
# #
# - 04.05.2018 by Herbert Schill: #
# #
# - remove bug in 'ReadDobsonLV': proper error message setting #
# #
# #
# - 07.05.2018 by Herbert Schill: #
# #
# - 'ReadDobsonAE': read all ozone values (5 or 6) from input-file #
# #
# #
# - 06.09.2018 by Herbert Schill: #
# #
# - 'WriteDobsonAE': headerline format depending of dN-values #
# #
# #
# - 09.01.2019 by Herbert Schill: #
# #
# - 'WriteDobsonAE': remove bug for proper airmass-values my: #
# if R<=19.9 then my='/' instead of my=0.000 #
# #
# #
# - 30.01.2019 by Herbert Schill: #
# #
