Bob and Thom:

It took some looking but ... here are the assignments from our previous deployment on 4/26 (FOCE/MARS4).

Bob,

Here are the pH calibration coefficients, along with serial number and SSDS (ISSI) ID's as well as location on the FOCE frame.    Please let Ed know when this has been built into the FOCE app.

Let me know if I can help.



Location	Serial #	SSDS		Calibration
----------  --------   ------       -----------------------------
FOCE pH #1	180358A	1724		slope= 9.5287, offset= 2.6129
FOCE pH #2	180512A	1735		slope= 9.8988, offset= 2.6233
FOCE pH #3	180513A	1722		slope= 9.8170, offset= 2.6404
FOCE pH #4	180514A	1725		slope= 9.7577, offset= 2.6290
FOCE pH #5	180511A	1734		slope= 9.8334, offset= 2.6086
FOCE pH #6 	180507A	1750		slope= 9.9380, offset= 2.6287

-------- backup spares, not on FOCE frame --------------

Spare 1     180506A	1749		slope= 9.8211, offset= 2.5793
Spare 2	180508A	1751		slope= 9.8575, offset= 2.6704

Ed,

I still need to get ISSI id's (those 4 digit numbers for SSDS) for the new sensors.   I'll work with PeterW on agreeing to a map for the sensors.

I'll work with Tom O on getting the coefficients built into the FOCE application (by tomorrow).

I will also write the calibration coefficients into the flash memory on each of the pH sensors as backup traceability.

FOCErs:

I've completed the number crunching on the HRpH sensors for our next FOCE deployment.  They all looked very good and had very fast response times -- got to love new electrodes...

Anyway, the calibration constants are attached for those who need to know.

Now, does someone have a map of which sensors went where so we know how to assign these constants?

Ed.
