Detailed Description

module to determine the appropriate manual p-cal phases offsets for each
station during an experiment w.r.t to a network reference station

Function Documentation

channel_sort_key()

def vpal.ffres2pcp_lib.channel_sort_key

(

ch_val_pair

)

sort channel value pairs in channel order

compute_final_pcphases()

def vpal.ffres2pcp_lib.compute_final_pcphases	(		apriori_pc_phases,
			generated_pc_phases
	)

given both the a-priori and generated SingleStationPCPhases, sum and round their values
to obtain the corrections necessary for the control file output

compute_vgos_network_reference_station_pc_phases()

def vpal.ffres2pcp_lib.compute_vgos_network_reference_station_pc_phases	(		single_baseline_pp_collection_obj,
			network_reference_station,
			discard_tolerance = 15.0,
			complete_discard_count = 5
	)

 compute the (Y-pol) pc_phases corrections for the station being used as the network reference station 

construct_control_file_lines()

def vpal.ffres2pcp_lib.construct_control_file_lines	(		apriori_pc_phases,
			generated_pc_phases,
			frequency_group = 'X',
			mode = 'VGOS'
	)

given both the a-priori and generated SingleStationPCPhases, sum and round their values
to obtain the corrections necessary for the control file output, then output formatted lines 

generate_ffres2pcp_control_file()

def vpal.ffres2pcp_lib.generate_ffres2pcp_control_file	(		config_obj,
			output_control_filename
	)

create the control file with the necessary pc_phases correction lines 

generate_pc_phases()

def vpal.ffres2pcp_lib.generate_pc_phases	(		config_obj,
			report_data_obj = None
	)

 main function for ffres2pcp to generate the pc_phase corrections for each station-pol (not including the apriori pc_phases)
this function does:
#(1) batch fourfits all of the available scans/baselines
#(2) combines the generated fringe files into collections
#(3) applies some selection critera to the collections to generate a list of scan collections for each station
#(4) extracts the pc_phases for each individual station from the selected scans
#(5) merges the reference station pc_phases (from all baselines/stations)
#(6) applies sigma cut to phase correction data
#(7) returns a dictionary of SingleStationPCPhases indexed by (station,pol) tuples 

generate_station_phase_corrections()

def vpal.ffres2pcp_lib.generate_station_phase_corrections	(		SingleBaselinePolarizationProductCollection_list,
			target_station,
			network_reference_station,
			dtec_tolerance = 1.0,
			network_reference_station_pol = 'X',
			discard_tolerance = 15,
			nchannel_discard_threshold = 5
	)

 function to generate pc_phases for station in an experiment
from a list of selected scans (gathered into SingleScanBaselineCollection) 

get_apriori_pc_phases()

def vpal.ffres2pcp_lib.get_apriori_pc_phases

(

ffres2pcp_config

)

 parse the control file and get the (a-priori) pc_phases which are already present 

select_collection_subset()

def vpal.ffres2pcp_lib.select_collection_subset	(		SingleBaselinePolarizationProductCollection_list,
			target_station,
			network_reference_station,
			dtec_nom = 0.1,
			max_number_to_select = 0
	)

this function selects single scan baseline pol-product collections for a particular target/reference station based on empirical method
this assumes cuts in min_snr, dtec deviation, etc. have already been made

sum_mean_pc_phases()

def vpal.ffres2pcp_lib.sum_mean_pc_phases	(		pcp_obj_a,
			pcp_obj_b
	)

sums the mean phases of the two SingleStationPCPhases objects and
returns a channel indexed dictionary of the summed values
