This data was provided to me on January 2016 by Philipe Amram. Who also provided the following parameters for the calibration:

calibration_wavelength = 6598.953125
finesse = 26
free_spectral_range_A = 11.410
interference_order = 609
interference_reference_wavelength_A = 6562.7797852
pixel_size_micron = 15
scanning_wavelength_A = 6760.89

The reduction was made using Tuna version 0.16.4. The code to reduce the image was:

import tuna

tuna.log.set_path ( "/home/nix/tuna.log" )
tuna.log.verbose ( "file", "DEBUG" )
tuna.log.verbose ( "console", "INFO" )

def reduce_calibration ( can ):
  reducer = tuna.pipelines.calibration_lamp_high_resolution.reducer (
    best_ring_plane = 28,
    calibration_wavelength = 6598.953125,
    finesse = 26,
    free_spectral_range = 11.410, # computed at the interference_reference_wavelength_A
    interference_order = 609, # computed at the interference_reference_wavelength_A
    interference_reference_wavelength = 6562.7797852,
    min_rings = 1,
    pixel_size = 15, # in microns
    scanning_wavelength = 6760.89,
    channel_subset = [ ],
    continuum_to_FSR_ratio = 0.25,
    noise_mask_radius = 8,
    dont_fit = False,
    tuna_can = can,
    unwrapped_only = False,
    verify_center = None )
reducer.join ( )
return reducer

cube = tuna.io.read ( "/home/nix/store/fpdata_SOAR_Philippe_Amram_2016-01-14/cal.ad3" )
pipeline_result = reduce_calibration ( cube )
tuna.tools.plot_high_res ( pipeline_result )

Output from ipython was:
