Detailed Description

Analaysis segment and meta data about size of segment, location in full data stream, and LISA observation parameters.

The Data structure stores information about the data being analyzed, including size of data, where it is located in the full LISA band, information about gaps, etc.

The structure stores the Fourier-domain TDI data channels, and a fiducial model for the instrument noise. It also has memory allocated for storing the reconstructed waveforms, residuals, and noise models.

◆ format

char Data::format[16]

Convention for data format.

format = "phase" for phase difference (distance) format = "frequency" for fractional frequency (velocity) Use for matching LDC Radler format = "sangria" for fractional frequency w/ LDC Sangria-era TDI & phase conventions

The documentation for this struct was generated from the following file:
