 Description   

The purpose of this taks is to answer the questions posed by Graham in this email, answering about my inquiry about strong flux seen in the data when no stop is used in the dummy cable B.

1. Is this a uniform effect seen across all fibres, or is there a significant fibre to fibre variation?
2. Do you see a similar scale of effect over the full wavelength range, or is there a variation with wavelength?

I will update this more, but there seems to be no dependence with fiber nor wavelength.

Comment by ncaplar [ 14/Jun/19 ]

As a function of fiber, from left to right, the ratio of flux seems to not have any dependence. The values I deduced from a single spot roughly in the middle of wavelength range are [2.99,2.85,3.08,3.08,2.40,3.07,2.96,3.07,3.05,2.58.]

Comment by ncaplar [ 14/Jun/19 ]

There also does not seem to be any wavelength dependence. The same ratio, as a function of y postion of the detector:
[889, 2.85]
[1369, 2.47]
[1659, 3.07]
[1757, 2.874]
[2375, 2.89]
[2853, 2.16]
[3393, 3.62]
[4023, 3.21]
