3. Characterization
|
Has this particular
instrument been characterized (determination of the deviations from
ideal behaviour)? |
yes no |
If
checked 'yes', answer the following question, if checked 'no'
go on to paragraph f) and give only an estimated uncertainty. |
|
a) Cavity reflectance:
|
ER
= |
+ / - |
Method
of determination: |
|
|
b) Difference in response
between radiation and electrical heating (non-equivalence, e.g.
different temperature distribution in the cavity, resistance of black
coating, aperture heating, etc.):
|
EHE
= |
+ / - |
Method
of determination: |
|
|
c) influence of diffraction
and straylight in view limiting device:
|
EST
= |
+ / - |
Method
of determination: |
|
|
d) Lead heating
|
ELE
= |
+ / - |
Method
of determination: |
|
|
e) Any further deviations
if applicable:
