Model properties
-
Target: quiet Sun, plage.
-
Grid points: 70 (models A,C,F) or 66 (model P)
-
Height range (z): 100km below optical depth unity (top of convection zone) to 1740km-2277km (depending on the model). Please note that the height axis is reversed with negative values in the atmosphere and positive values in the convection zone.
-
Grid resolution, vertical:variable.
-
Magnetic field: none
Available model data
Four different models for different regions are provided in the directory https://astro-sdc-db.uio.no/vol/ssalmon/fal/.
ID | type of region | link | points |
---|---|---|---|
A | Quiet Sun, faint | astro-sdc-db.uio.no/vol/ssalmon/fal//fala.dat | 70 |
C | Quiet Sun, average | http://astro-ursafs.uio.no/vol/ssalmon/fal/falc.dat | 70 |
F | Quiet Sun, bright | http://astro-ursafs.uio.no/vol/ssalmon/fal/falf.dat | 70 |
P | Plage, typical | http://astro-ursafs.uio.no/vol/ssalmon/fal/falp.dat | 66 |

* Quantities ordered in the same way as in the data files (and tables in the original paper).
How to load the data in IDL: The data is tabulated in ASCII with a fixed format with 6 columns (see table above), which can easily read with the built-in routine READ_ASCII:
data=read_ascii(filename)
The variable data will contain a data structure and some unwanted lines due to the comment lines in the file. You can get rid off these by:
data=data.field1[*,1:70]
for models A,C,F or
data=data.field1[*,1:66]
for model P.
