NAME
rcamera -- Convert Kitt Peak CAMERA image files to IRAF image files
USAGE
rcamera [camera_file, file_list, iraf_file]
DESCRIPTION
Kitt Peak CAMERA format image data is read from the specified
source; either a disk file or magnetic tape. The CAMERA header may
optionally be printed on the standard output as either a full
listing or a short description. Image data may optionally be
converted to an IRAF image of specified data type.
PARAMETERS
camera_file
The CAMERA data source. If the data source is a disk file or
an explict tape file specification of the form mt*[n] where n
is a file number then only that file is converted. If the
general tape device name is given, i.e. mta, mtb800, etc, then
the files specified by the files parameter will be read from
the tape.
file_list
The files to be read from a tape are specified by the file_list
string. The string can consist of any sequence of file numbers
separated by at least one of whitespace, comma, or dash. A
dash specifies a range of files. For example the string
1 2, 3 - 5,8-6
will convert the files 1 through 8.
iraf_file
The IRAF file which will receive the CAMERA data if the
read_image parameter switch is set. For tape files specified
by the file_list parameter the filename will be used as a
prefix and the file number will be appended. Otherwise, the
file will be named as specified. Thus, reading files 1 and 3
from a CAMERA tape with a filename of data will produce the
files data1 and data3. It is legal to use a null filename.
make_image
This switch determines whether CAMERA image data is converted
to an IRAF image file. This switch is set to no to obtain just
header information with the long_header or short_header
switches.
long_header
If this switch is set the full CAMERA header is printed on the
standard output.
short_header
If this switch is set only the output filename, the title
string, and the image dimensions are printed.
standard_format
The CAMERA standard format has the least significant byte
first. Some CAMERA data, however, does not follow this byte
order convention. Thus, to read the non-standard CAMERA data
this parameter is set to no.
datatype
The IRAF image file may be of a different data type than the
CAMERA image data. The data type may be specified as s for
short, l for long, r for real, and d for double. The user must
beware of truncation problems if an inappropriate data type is
specified. If an incorrect data_type or a null string is given
for this parameter then a default data type is used which is
the appropriate minimum size for the input pixel values.
