Hi Steph,
There are some .fits data and log sheets that need your help at
/ftp1/Mike/HI-2020-01/
These are BS05cfg101 and RS05cfg101 bare FO #6 laser scans, via the repaired Ekspla-cfg10 = laser data Ken requested during the build of the next BS/RS instrument.  There are 3x days of data so far.

As that kine "HI-2020-01_2xSiPDs(20200205,MF).pdf" tried to express, iHave been running 2x Si PhotoDiode monitors on the Spectralon sphere. iDon't know that you should put much energy into trying to process the *Keithley.txt files - they are very preliminary attempts to integrate charge via the Keithley Electrometer.  All charge integrations are over a time period of 1 power line cycle (PLC) which has to do with the 60 Hz cycling of AC power.  The charge integration time will eventually be dictated by a precision shutter between the Ekspla laser and the integrating sphere. The reason we need to integrate charge from the PDs - rather than just convert Amperes current output to DC Volts via a pre-amp and measure Volts via a DVM - is that the Ekspla output is pulsed, at 1000 Hz, and the ole-kine PD + pre-amp approach cannot keep up with a pulsed signal.

Once we see if these first 3 days data look reasonable, then the BS5&RS5 will go to Mark & Riley to begin build-up - with shutters and filters and
axu boards, etc.

Luck eh!  MF

Hi Steph,
There are HI-2020-01 day4 data @ the NAS for thee!
iScanned a couple more nUV BS lines with the 2nd order peak on-CCD,
and iGot saturation scans @ centre-CCD waves for BS & RS.

FYI, the VpN still did not want that complicated password to map network drive...
Cheers, MF

Thanks youse Stephs,
iShalls have a looks at day4 plots next.
iHave some day5 data at the NAS for thee -
your comment r.e. a broad-band source for flat-window-ghost viewing
got me thinking... so iSetup the Oriel incandescent source today.
There are also some day5 photos to go with the .fits & log sheet files.
iSuspect that this could be the end of the bare-FO BS/RS kine for now.
Aloha, MF

iHad not noticed this before but perhaps you did...
from your raw data fig.8 plots it looks like the 2nd order peak from nUV input
is somewhat off-centred from the track-pixel range defined by 1st order peaks -
sort of like how a saturated scan blooms outside the normal track-pixel range -
is this truth?
Maybe "we" need some zoomed in plots of the 2nd order peaks?

iAm also thinking that iWould like to see BS scans between 320 and 350nm
to see at what input wave the 2nd order peak first appears...
I.E. is there any off-CCD waves that give on-CCD 2nd order?

Did you notice this curiousity in the BS near-IR @ big saturation?

The RS, it don't do that.

iThink the shoulder plots from the saturated kine are my favourites!

One more ting:
For the BS off-ccd scans, @ 300 & 320nm,
there are the funny bumps between spectral-pixels 50 & 250 -
which seem to stay in the same place, for scans at 300,320,350nm input,
and maybe kinda also at 355nm, but are pretty much lost @ 360,325.5nm,
but may be there at 365nm.

I'm wondering if could you please overplot these 300:365 scans to see
if these funny bumps are stationary?

iAm wondering if these may have something to do with the possible
laser and/or sphere fluorescence that iWant to go a hunting for...

Thanks,MF

Hi Steph,
iHope you have not yet processed day5, because
iJust added some more BS scans, .fits # 13:40,
to look at the 2nd order from n-UV lines.
There is also a revised BS log sheet "HI-2020-01_BS05log_day05.jpg"
and a revised "HI-2020-01_MFnotes_20200210-01.jpg" at HI-2020-01\doc\.
Sorry.
MF

Hi Steph,
There are day6 BS5&RS5 data for you at the NAS /ftp1/Mike/HI-2020-01/
iJust did a quick scan set via Room124 overhead fluorescent lighting,
with all 14x bare FOs pointing at a piece of white packing foam, so,
the spectral coverage is not continuous, and
does not cover the ends of BS nor RS CCDs.

If this these data are OK for your track defs, then
could you please let Mark and Riley know it is OK for them to continue
their instrument build up?

If, however, these data are not good enough, then iShall try again tomorrow.
Thank you, MF
