Fenix Calibration, 2015

[lah]

Data location: ~arsf/arsf_data/2015/misc/2015_cal_feb_gloucester

[lah]

Produced wavelength scale with parameters below, removing bad lines (from fityk output .peaks files) with unrealistic FWHMs and large errors from spectral line test:

config file (/processed_lah/calibration_config.cfg):

• day: d3-1
• linefile: spectral_lines_aug15.csv
• sample_hdr_file: /users/rsg/arsf/calibration/2014/fenix/fenix_201405.hdr

cal_spectral.py:

• --hwhm
• --offset2 -8

final anchors: -1.3922212, -9.664062
final VNIR start: 379.792 nm
final SWIR start: 970.172 nm

All processing files stored in /processed_lah. Analysis outputs stored in /results (dated Sept 16).

[dac]

Redid spectral calibration using initial offset of -5.6, as found from comparison of minima in Fenix data from 2014, all processed with old calibration.

Final anchors: -0.929688, -6.546777
final VNIR start: 380.255 nm
final SWIR start: 969.272 nm

Processing stored under ./processed_sept_dac

Used '20150812_lah_cal_fixes' branch.

Continuing to radiometric calibration

[lah]

Original calibration of 9nm offset had SWIR band starting at 967.348 nm, so not convinced that either of these calibration files is ideal.

[dac]

Generated bandsets for VNIR binning of 4 and 8 using:

gen_bandsets.py --sensor fenix -b 2 -o fenix_201509_vnirbinning4 fenix_201509.txt --makesourcefile
gen_bandsets.py --sensor fenix -b 4 -o fenix_201509_vnirbinning8 fenix_201509.txt --makesourcefile

'Bad pixel File'

Generated bad pixel file using config settings below. Removed +1 from autodarkstartline in badpixel_detection script, as was using a line of the dark frames in calculations, particularly affecting method A.

B_thresh = 10
C_thresh = 0.9825
D_spectralwidth = 1

D_thresh = 3
F_thresh = 0.1
