muniphot

NAME

muniphot - utility for photometry of CCD frames

SYNOPSIS

muniphot [ options ] input-files ...

DESCRIPTION

The muniphot command applies photometry to a single frame or a set of CCD frames. The output is written to so-called photometry files.

Current version uses aperture photometry algorithm only. All source frames must be in the FITS format.

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=kout????.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.

readns = value

Readout noise

gain = value

ADC gain

minvalue = value

Min. pixel value in ADU

maxvalue = value

Max. pixel value in ADU

fwhm = value

Expected FWHM in pixels

thresh = value

Detection threshold

minsharp = value

Low sharpness cutoff

maxsharp = value

High sharpness cutoff

minround = value

Low roundness cutoff

maxround = value

High roundness cutoff

skyinner = value

Inner radius of sky aperture

skyouter = value

Outer radius of sky aperture

apertures = value,value,...

Comma separated list of radii of star apertures

EXAMPLES

muniphot -oout?.pht test1.fts test2.fts test3.fts

The command performs photometry to the files test1.fts, test2.fts and test3.st7 and writes the output to the files: out1.pht, out2.pht and out3.pht.

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.
