Function Documentation

findSensorsChannels()

void findSensorsChannels	(	const std::string &	filename,
		std::vector< std::string > &	sensors,
		std::vector< int > &	nchannels
	)

Finds all sensors in the file (returned in sensors) and number of channels for all the sensors (returned in nchannels)

Read the first entry, save first sensor

readObsBiasCoeffErrors()

void readObsBiasCoeffErrors	(	const std::string &	filename,
		const std::string &	sensor,
		std::vector< int > &	channels,
		Eigen::ArrayXXf &	errs,
		Eigen::ArrayXf &	nobs
	)

Read bias coefficients errors from the GSI file (satbias_pc)

Parameters

filename	file with bias coefficients (GSI style)
sensor	instrument+satellite that is to be read from the file
(out)	channels channels for sensor
(out)	errs bias coefficients error variances
(out)	nobs number of observations

it's the sensor we're interested in; read in coefficients and channel indices

not interested in this channel; passing

	)

Read bias coefficients from the GSI bias coefficients file (satbias_in)

Parameters

sensor	instrument+satellite that is to be read from the file
(out)	channels channels for sensor
(out)	coeffs bias coefficients
