6 meanbias - utility for making master-bias frames

9 meanbias [ options ] output-file input-files ...
10
12 The meanbias command compose a set of bias frames and makes one bias
13 frame called ´master-bias´. Applying this function, you can achieve
14 high quality correction frame and thus reducing the noise of a
15 result. The bias correction is applied in advanced calibration scheme
16 only, please refer to documentation about the calibration of CCD
17 frames.
18
19 All source frames must be in the FITS format and of same dimensions.
20 The output file is written in the FITS format too.
21
23 Names of input files can be specified directly on a command-line as
24 command arguments; it is allowed to use the usual wildcard notation. In
25 case the input files are placed outside the working directory, you have
26 to specify the proper path relative to the current working directory.
27
28 Alternatively, you can also prepare a list of input file names in a
29 text file, each input file on a separate line. It is not allowed to use
30 the wildcard notation here. Use the -i option to instruct the program
31 to read the file.
32
34 Options are used to provide extra information to customize the execu‐
35 tion of a command. They are specified as command arguments.
36
37 Each option has a full form starting with two dashes and an optional
38 short form starting with one dash only. Options are case-sensitive. It
39 is allowed to merge two or more successive short options together. Some
40 options require a value; in this case a value is taken from a subse‐
41 quent argument. When a full form is used, an option and its value can
42 also be separated by an equal sign. When a short form is used, its
43 value can immediately follow the option.
44
45 Whenever there is a conflict between a configuration file parameter and
46 an option of the same meaning, the option always take precedence.
47
48 -s, --set name=value
49 set value of configuration parameter
50
51 -i, --read-dirfile filepath
52 read list of input files from specified directory file; see the
53 Files section for details.
54
55 -p, --configuration-file filepath
56 read parameters from given configuration file. See the Configu‐
57 ration file section for details.
58
59 -h, --help
60 print list of command-line parameters
61
62 -q, --quiet
63 quiet mode; suppress all messages
64
65 --version
66 print software version string
67
68 --licence
69 print software licence
70
71 --verbose
72 verbose mode; print debug messages
73
75 Configuration files are used to set the input parameters to the process
76 that is going to be executed by a command. Use the -p option to
77 instruct the program to read the file before other command-line options
78 are processed.
79
80 The configuration file consists of a set of parameters stored in a text
81 file. Each parameter is stored on a separate line in the following
82 form: name = value, all other lines are silently ignored. Parameter
83 names are case-sensitive.
84
85 bitpix = value
86 output data format (0=Auto)
87
89 meanbias out.fts in1.fts in2.fts in3.fts
90 The command computes the master-bias frame from the input files
91 in1.fts, in2.fts a in3.fts; the resulting frame is stored to
92 output file out.fts.
93
95 The command returns a zero exit status if it succeeds to process all
96 specified files. Otherwise, it will stop immediately when an error
97 occurs and a nonzero error code is returned.
