NAME

meandark - utility for making master-dark frames

SYNOPSIS

meandark [ options ] output-file input-files ...

DESCRIPTION

The meandark command compose a set of dark frames and makes one dark frame called 'master-dark'. Applying this function, you can achieve high quality correction frame andthus reducing the noise of a result.

All source frames must be in the FITS format and of same dimensions. Frames of the same exposition duration should be used. 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.

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.
-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.

bitpix = value
output data format (0=Auto)
scalable = value
make scalable dark-frame (0=No, 1=Yes)

EXAMPLES

meandark out.fts in1.fts in2.fts in3.fts
The command computes the master-dark frame from the input files in1.fts, in2.fts a in3.fts; the resulting frame is stored to 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.
