| Proj. U | - Projected umbra area in millionths of solar disc, negative values indicate | |
|
that the umbra consists of fragmented regions which cannot be separated without losing umbral area. In this way several spots (intensity minima in the umbra) have a common umbra, e.g. -2 means that the given spot shares an umbra with spot No.2, and the common U value is indicated at spot No.2. |
||
| Proj. WS | - Projected whole spot area in millionths of solar disc, negative values indicate | |
|
that several umbras have a common penumbra, e.g. -7 means that the given umbra shares a penumbra with umbra No.7, and the WS value is indicated at No.7. |
||
| Corr. U | - Corrected umbra area in millionths of solar hemisphere, for negative values see above | |
| Corr. WS | - Corrected whole spot area in millionths of solar hemisphere, for negative values see above | |
| B | - Heliographic latitude B; positive: North, negative: South | |
| L | - Heliographic longitude L | |
| LCM | - Longitudinal distance from the Sun's central meridian | |
| Pos. angle | - Position angle | |
| r | - Distance from the centre of Sun's disc in terms of Sun's radius | |
| MU | - Mean magnetic field within the umbra contour averaged the pixel values with sign. | |
| MP | - Mean magnetic field within the penumbra contour averaged the pixel values with sign. | |
