Hi,
1) I understand that in high res mode the device produces data at every 10/3nm.
Is the
data processed by Argyll/drivers in any way before being written to the file
and if so how?
yes of course - the data from the instrument is raw sensor values, so the
driver has to do a bunch of processing to convert this to calibrated values.
2) Would you recommend processing the output data in the file and if so how?
I'm not sure what you mean. The results are calibrated spectral values. Only
you know what you want to do with them after that.
3) Are sampling intervals other than 10/3nm and 'standard' available to
spotread and if so
what's the relative switch?
No. These are what are implemented in the ArgyllCMS driver. There seems little
point in attempting to go below 3.333 nm, as this is the closest regular
spacing to
the sensor capability itself, and in any case the spectral resolution is
limited by the slit width. You can of course resample to larger spacings
using the usual methods (i.e. those recommended in the CIE specs.).
Hope this helps,
Graeme Gill.
