Linear Phase Compensation

INFOS will calculate lineshapes that incorporate distortions due to delay in acquisition, followed by linear phasing to correct for those delays. This is activated by specifying the size of the linear phase correction (in degrees, see 2.3.1), but can be deactivated by setting ‘par.dX.LPC’ to ‘n’ or 0. The delay is calculated as

t_delay=-(PHC1/360)/SWH0

where ‘PHC1’ is the provided phase (difference of phase from left to right side of spectrum before truncation), and ‘SWH0’ is the sweep width of the spectrum (in Hz, before spectrum truncation).
