dbcreate namedata
Parameters
- namedata
- This is the name of the new database file. The resulting file will be saved automatically with the leading "sf" extension in the current directory.
- low_mult
- This number multiplied by the parameter value will create the default lower limit.
- high_mult
- Same as low_mult but used to create the upper parameter limit.
- step_mult
- Used to create the default step size.
- comp_name
- Enter the name for the type of component desired. See the help for "specfit" for a description of the available component types.
- comment
- A descriptive comment for this component may be entered. For example, "Broad component of Halpha emission".
- parambool
- yes or no. Used to affirm a correct entry.
- parameters
- Enter the number of parameters associated with the chosen component type. See the help for "specfit" for details.
- new_par_value
- The value for the new parameter to be entered in the database.
- lower_limit
- Lower limit for the new parameter
- upper_limit
- Upper limit for the new parameter
- step_size
- Step size for the new parameter
- param_tolerance
- Tolerance for the new parameter. Values of 0.01 to 1.e-6 are recommended.
- fix_or_free
- For freely varying parameters, enter 0. For fixed parameters, enter -1. For parameters linked to another component, enter the positive integer giving that component's number. (See the help for specfit for details on linking.)
Description
This program will create a database file for use by specfit. It will prompt you for all the required values and write out the new database in the correct format. This is a simpler and more error-free method for creating a new database than the usual way of editing a text file. It calls the task dbcheck to verify the new database file.
