pypeit.scripts.show_wvcalib module

Wrapper to matplotlib to show an arc spectrum

class pypeit.scripts.show_wvcalib.ShowWvCalib

Bases: ScriptBase

classmethod get_parser(width=None)

Construct the command-line argument parser.

Derived classes should override this. Ideally they should use this base-class method to instantiate the ArgumentParser object and then fill in the relevant parser arguments

Warning

Any argument that defaults to the string 'current working directory' will be replaced by the result of Path.cwd() when the script is executed. This means help dialogs will include this replacement, and parsing of the command line will use Path.cwd() as the default. This functionality is largely to allow for PypeIt’s automated documentation of script help dialogs without the “current working” directory being that of the developer that most recently compiled the docs.

Parameters:

• description (str, optional) – A short description of the purpose of the script.

• width (int, optional) – Restrict the width of the formatted help output to be no longer than this number of characters, if possible given the help formatter. If None, the width is the same as the terminal width.

• formatter (argparse.HelpFormatter) – Class used to format the help output.

• include_log_options (bool, optional) – Include options that define the logging level(s) and log file.

• default_log_file (bool, optional) – If true, script will use the default log file name if none is provided. Ignored if include_log_options is False.

Returns:

Command-line interpreter.

Return type:

argparse.ArgumentParser

classmethod main(args, unit_test=False)
