Compilation of Surface Brightness

| HyperLeda home | Documentation | Search by name | Search near a position | Define a sample | SQL Search |

Field: mu

The surface brightness in magnitudes per square arcsec (mag arcsec^-2)

Field: code_mu

Code for the type of surface brightness

0
Central or peak surface brightness

1
Surface brightness at effective radius

2
Effective mean surface brightness within the effective radius (equivalent radius in which half the total flux is emitted).

3
Central surface brightness for exponential fit

Field: quality

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

Field: bandname

Photometric Band. The definitions are given in the "band_codes" table:
