NB - NB: Please note that the
correct CCD names are : |
|
| CCD
Name : |
Tucana |
|
| Grade : |
|
Science |
|
Tucana (serial no: 02395-20-01) and not Alcor as the data
files are called. |
|
| Serial
Number : |
02395-20-01 |
|
Triangulum Australe ( serial no: 02395-19-01) and not
Alcalurops as the data files are called. |
|
| Type
: Backside, Single layer AR Pixel size 15 x 15 μm |
|
| Number
of photosensitive pixels 2048 x 4102 [HxV] |
|
When the CCD's was tested they were given the wrong name
and therefor all the datafiles used |
|
| Number
of outputs : 2 |
|
this wrong name. Test reports etc. have a note about this
issue. |

|
| In this section
we expose the hot pixel, the dark pixel, the trap and the very large trap
we have found. |
|
|
| Hot
pixel |
A hot
pixel provides a signal of > 60 e- / pixel
/ hour. |
|
|
|
| Very
bright pixel |
a very bright pixel provides
a signal of > 200000 e-/pixel/hour |
|
|
|
| Dark
pixel |
A dark pixel is one with 50% or less than the average output for uniform
intensity light level, measured with a flat field level around 500 photo-electrons |
|
|
|
| Trap |
A trap is defined as a pixel that captures more than 10 electrons,
measured with a flat field level around 500 photo-electrons. |
|
|
|
| Very
large trap |
A very large trap is defined as a pixel that captures more than 10 000 electrons,
measured with a flat field level around 90% of full well capability. |
|
|
|
| Bad
column |
A bad column is 10 or more contiguous hot
or dark pixels in a single column or a very bright pixel or a very large trap. |
