Code for the type of surface brightness
0

|
1
|
Surface brightness at effective radius |
2

Quality Flag
The quality flag has the following meaning:
| description of quality flag |
|---|
| value | signification |

| 0 | regular measurement |
| 1 | uncertain measurement, its weight is decreased by a factor 2 when computing the average value |
| 3 | preliminary measurement, probably superseeded in a more recent publication, it is ignored unless no other measurement is available |
| 4 | compilation, it is ignored unless no other measurement is available |
| 9 | rejected measurement |
