The data are horribly degraded any time the ship steams, so any data collected while the ship was moving has been deleted. Calibration is based on bottom track from leg 1 and appears to be sufficient PROCESSOR : J.Hummon --- processing parameters ---------- ## (determined from "sonar"): model = wh ## (determined from "sonar"): frequency = 300 ## (determined from "sonar"): pingtype = bb ## (determined from "sonar"): instname = wh300 badbeam None beamangle 20 configtype python cruisename MV1305 datatype uhdas dbname aship ens_len 300 fixfile aship.gps hcorr_inst coda_f185 pgmin 50 proc_engine python ref_method refsm sonar wh300 yearbase 2013 Process UHDAS data using Python ============================================= In order to use all-python processing, we will generate the configuration file necessary from modern ship's settings and edit as needed. This file will be (a) consistent with all-python processing (b) guarantees newest file format (c) is more flexible (0) make a directory for processing, configuration, and notes: mkdir mv1305 cd mv1305 (1) # in mv1305 copy the config files: rsync -axl /home/data/uhdas_data_archive/melville/MV1305_legs/MV1305/proc/wh300/config . verify that MV1305_proc.py is correct ### save file; exit editor # go back one level cd .. (2) now we can use that file. Set up the processing directory by typing: adcptree.py wh300 --datatype uhdas --cruisename MV1305 NOTE: Now there is no error message about missing configuration files (3) (a) change directories to ADCP processing directory just created cd wh300 NOTE: there is a "config" directory and it has a copy of the file mv1305_proc.py that we created in #2 (b) create a quick_adcp.py control file unix: this example is written as a bash "heredoc" for cut-and-past ease, but you can create q_py.cnt with an editor to have the parts between (or including) the comments cat << EOF > q_py.cnt ####----- begin q_py.cnt------------ ## all lines after the first "#" sign are ignored --yearbase 2013 --cruisename MV1305 # used to identify configuration files # *must* match prefix of files in config dir --update_gbin ## NOTE: You should generally remake gbins ## - you are not sure ## - if parameters for averaging changed ## - various other reasons. ## ==> MAKE SURE you move the original gbin directory ## to another name first!! #--py_gbindirbase gbin # (will put them adjacent to q_py.cnt) --configtype python ## <=== USE THE NEW FILE WE CREATED --sonar wh300 --dbname aship --datatype uhdas --ens_len 300 --ping_headcorr ## applies heading correction. ## settings found in config files --proc_engine python ## use python to do calculations --max_search_depth 3000 #if the topography says the ocean is deeper # than this, do not autodetect the bottom. # (reduces likelihood of shallow scattering # layers being identified as the bottom) EOF (c) run quick_adcp.py: quick_adcp.py --cntfile q_py.cnt ================================================================== -not correcting heading gaps -deleting all underway data, and the edges of the onstation data -agreement with os75bb in upper bins is poor, but it's not actually clear which is at fault. -no additional calibration. -web plots: mkdir webpy cp ../os75nb/webpy/sectinfo.txt webpy quick_web.py --redo
