The common options of the image-mapping process contains the names of I/O files

source

The input HDF file name.
The input file could be population data or the pure model data when operating LTE / continuum / column density mapping

out

The output FITS file name.

to set up the observing position by the distance and the rotation of the model by the two flags

dist

The distance, on x-direction, of the observing point from the model. e.g. ‘1kpc’

rotate

Three arguments of angular parameter to rotate the model counter-clockwise sequentially by x-, y-, z-axis of the model’s coordinate

to set up the resolution and the configuration of the map by the flags:

cell

The angular size of one pixel cell

npix

The number of the pixels

subres

The sub-sampling of some specific region

For molecular line and Zeeman image

line

The index of molecular line transition

lte

LTE or non-LTE option

chan

The resolution and the range of the velocity channel

For continuum image

wavelen

The wavelength of the radiation
