xsnsmax

Context: models

Synopsis

The XSPEC nsmax model: Neutron Star Magnetic Atmosphere.

Syntax

xsnsmax

The xsnsmax model is an additive model component.

Description

The model is described at [1] . It has been superceeded by XSnsmaxg .


Example

>>> create_model_component("xsnsmax", "mdl")
>>> print(mdl)

Create a component of the xsnsmax model and display its default parameters. The output is:

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.logTeff  thawed            6          5.5          6.8          K
   mdl.redshift thawed          0.1        1e-05          1.5           
   mdl.specfile frozen         1200 -3.40282e+38  3.40282e+38           
   mdl.norm     thawed            1            0        1e+24           

ATTRIBUTES

The attributes for this object are:

LogTeff

redshift

This is 1 + zg, the gravitational redshift.

specfile

Which model to use: see [1] for more details.

norm

The normalization of the model: see [1] for more details.
