seasonder_CSSY_read_csign: Read Complex Spectral Sign Information from a Connection

In SeaSondeR: Radial Metrics from SeaSonde HF-Radar Data

Read Complex Spectral Sign Information from a Connection

Description

This function reads a raw binary stream from a provided connection, expecting a specific format that contains the sign bits for complex spectral values. The data is divided into 6 groups corresponding to: C13r, C13i, C23r, C23i, C12r, and C12i.

Usage

seasonder_CSSY_read_csign(connection, key)

Arguments

connection	A binary connection to read raw bytes from.
key	A list containing: size An integer specifying the total number of bytes to be read. It must equal 6 times the number of bytes per group. key A string identifier (expected to be "csign").

Details

The function performs the following steps:

• Reads key$size bytes from the specified connection.

• Checks if enough bytes were read.

• Ensures that the total number of bytes is divisible by 6, allowing equal distribution among the groups.

• Splits the raw byte vector into 6 groups based on the calculated number of bytes per group.

• Converts each byte into its 8-bit representation (using rawToBits) and flattens the result.

Value

A named list of 6 vectors. Each vector represents one group (e.g., C13r, C13i, etc.) and contains integers (0 or 1) corresponding to the bits (in little-endian order) extracted from the raw data.
