Add support for old HyperOCRs that have no internal thermistor

[oceancolorcoder]

HyperCP expects SeaBird radiometers to have an internal thermistor to provide the thermal correction, but older (pre-2008?) HyperOCRs do not have spectrometer temperature sensor (SPECTEMP) and their calibration files do not have CALTEMP or THERMAL_RESP.

This was raised in issue #371 which contains the relevant error messages from ~v1.2.14, including one work-around strategy until a more formalized approach is found.

If you have this problem, please reach out in the comments here and we may request a sample data/calibration set for testing.

Thanks!

Hi Dirk,

I do have HOCR that have this problem. I think Raphael already mentioned the problem in #371 discussion.

Thanks for your help.

I also have three radiometers (187, 250, and 251) and associated pySAS datasets that only have the TEMP_PCB fields and are missing the SPECTEMP, CALTEMP, and THERMAL_RESP fields. Let me know if I can help.
