5. Characterization
|
Has this particular instrument been characterized
(determination of the deviations from ideal behaviour)? |
yes no
|
If 'yes', answer the following questions, if 'no'
continue with paragraph g) and give only an estimated uncertainty. |
|
a) Area of aperture:
|
A= |
+ / - |
mm2 |
Method of determination: |
|
b) Cavity reflectance:
|
ER= |
+ / - |
Method of determination: |
|
|
c) 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: |
|
|
d) influence of diffraction and straylight in view limiting device:
|
EST= |
+ / - |
Method of determination: |
