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.

lower_limit

Lower limit for the new parameter

upper_limit

Upper limit for the new parameter

Step size for the new parameter

param_tolerance

Tolerance for the new parameter. Values of 0.01 to 1.e-6 are recommended.

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.
