NAME

darkbat - utility for dark correction

SYNOPSIS

darkbat [ options ] dark-file input-files ...

DESCRIPTION

The darkbat command applies dark correction to a set of source frames.

The source frames and the dark frame must be in the FITS format and of same dimensions. The output file is written in the FITS format too.

INPUT FILES

Names of input files can be specified directly on a command-line as command arguments; it is allowed to use the usual wildcard notation. In case the input files are placed outside the working directory, you have to specify the proper path relative to the current working directory.

Alternatively, you can also prepare a list of input file names in a text file, each input file on a separate line. It is not allowed to use the wildcard notation here. Use the -i option to instruct the program to read the file.

OUTPUT FILES

By default, output files are stored to the current working directory. Their names are derived from the command name followed by a sequential number starting by 1. Command options allows a caller to modify the default naming of output files:

The -o option sets the format string; it may contain a path where the files shall be stored to. Special meaning has a sequence of question marks, it is replaced by the ordinal number of a fileindented by leading zeros to the same number of decimal places as the number of the question marks.

By means of the -i option, you can modify the initial value of a counter.

On request, the program can write a list of output files to a text file, use the -g option to specify a file name.

OPTIONS

Options are used to provide extra information to customize the execution of a command. They are specified as command arguments.

Each option has a full form starting with two dashes and an optional short form starting with one dash only. Options are case-sensitive. It is allowed to merge two or more successive short options together. Some options require a value; in this case a value is taken from a subsequent argument. When a full form is used, an option and its value can also be separated by an equal sign. When a short form is used, its value can immediately follow the option.

Whenever there is a conflict between a configuration file parameter and an option of the same meaning, the option always take precedence.

-s, --set name=value
set value of configuration parameter
-i, --read-dirfile filepath
read list of input files from specified file; see the Files section for details.
-g, --make-dirfile filepath
save list of output files to specified file, existing content of the file will be overwritten; see the Files section for details.
-o, --output-mask mask
set output file mask (default=dout????.fts), see the Files section for details.
-c, --counter value
set initial counter value (default=1), see the Files section for details.
-p, --configuration-file filepath
read parameters from given configuration file. See the Configuration file section for details.
-h, --help
print list of command-line parameters
-q, --quiet
quiet mode; suppress all messages
--version
print software version string
--licence
print software licence
--verbose
verbose mode; print debug messages

CONFIGURATION FILE

Configuration files are used to set the input parameters to the process that is going to be executed by a command. Use the -p option to instruct the program to read the file before other command-line options are processed.

The configuration file consists of a set of parameters stored in a text file. Each parameter is stored on a separate line in the following form: name = value, all other lines are silently ignored. Parameter names are case-sensitive.

scaling = value
dark-frame scaling (0=disabled, 1=enabled)

EXAMPLES

darkbat -oout.fts dark.fts in.fts
The command applies the dark correction to the input file in.fts using the file dark.fts as a correction frame. The output is written to the output file out.fts.

EXIT STATUS

The command returns a zero exit status if it succeeds to process all specified files. Otherwise, it will stop immediately when an error occurs and a nonzero error code is returned.
