A CellMedium instance represents a transfer medium with a spatial density distribution (and, optionally, other properties) described by a list of cuboidal cells lined up with the coordinate axes; refer to the CellSnapshot class for more information. The cell data is usually extracted from a cosmological simulation snapshot, and it must be provided in a column text file formatted as described below.
Refer to the description of the TextInFile class for information on overall formatting and on how to include header lines specifying the units for each column in the input file. In case the input file has no unit specifications, the default units mentioned below are used instead. The number of columns expected in the input file depends on the options configured by the user for this CellMedium instance:
\[ x_\mathrm{min}\,(\mathrm{pc}) \quad y_\mathrm{min}\,(\mathrm{pc}) \quad z_\mathrm{min}\,(\mathrm{pc}) \quad x_\mathrm{max}\,(\mathrm{pc}) \quad y_\mathrm{max}\,(\mathrm{pc}) \quad z_\mathrm{max}\,(\mathrm{pc}) \quad \{\, \rho\,(\text{M}_\odot\,\text{pc}^{-3}) \;\;|\;\; M\,(\text{M}_\odot) \;\;|\;\; n\,(\text{cm}^{-3}) \;\;|\;\; N\,(1) \,\} \quad [Z\,(1)] \quad [T\,(\mathrm{K})] \]
\[ [ v_x\,(\mathrm{km/s}) \quad v_y\,(\mathrm{km/s}) \quad v_z\,(\mathrm{km/s}) ] \quad [ B_x\,(\mu\mathrm{G}) \quad B_y\,(\mu\mathrm{G}) \quad B_z\,(\mu\mathrm{G}) ] \quad [ \dots\text{mix family params}\dots ] \]
The first six columns specify the coordinates of the lower-left and upper-right corners of the cell. Depending on the value of the massType option, the seventh column lists the average mass density \(\rho\), the integrated mass \(M\), the average number density \(n\), or the integrated number density \(N\) for the cell.
If the importMetallicity option is enabled, the next column specifies a "metallicity" fraction, which is multiplied with the mass/density column to obtain the actual mass/density of the cell. If the importTemperature option is enabled, the next column specifies a temperature. If this temperature is higher than the maximum configured temperature, the mass and density of the cell are set to zero, regardless of the mass or density specified in the seventh column. If the importTemperature option is disabled, or the maximum temperature value is set to zero, such a cutoff is not applied.
If both the importMetallicity and importTemperature options are enabled, this leads to the following expression for the mass of an imported particle:
\[ M_\mathrm{imported} = \begin{cases} f_\mathrm{mass}\,Z\,M & \mathrm{if}\; T<T_\mathrm{max} \;\mathrm{or}\; T_\mathrm{max}=0 \\ 0 & \mathrm{otherwise} \end{cases} \]
If the importVelocity option is enabled, the subsequent three columns specify the \(v_x\), \(v_y\), \(v_z\) velocity components of the particle (considered as the bulk velocity for the mass represented by the particle).
If the importMagneticField option is enabled, the subsequent three columns specify the \(B_x\), \(B_y\), \(B_z\) magnetic field vector components for the cell.
Finally, if the importVariableMixParams option is enabled, the remaining columns specify the parameters used by the configured material mix family to select a particular material mix for the cell.

This function constructs a new CellSnapshot object, calls its open() function, configures it to import a mass or density column, it, and finally returns a pointer to the object. Ownership of the Snapshot object is transferred to the caller.
Implements ImportedMedium.

This function returns the value of the discoverable MassType enumeration property massType : "the type of mass quantity to be imported" .
The default value for this property is given by the conditional value expression "MassDensity" .
