rdumpf -- convert IPPS rasters from DUMPF tapes to IRAF images
rdumpf dumpf_file file_list iraf_file
IPPS rasters stored in DUMPF format are read and optionally converted to
IRAF images. The IPPS ID and other header information is printed.
The rasters to be converted are specified by both a file
number and then a raster number within that file. It may be helpful to
first run task ldumpf
to list the contents of the DUMPF tape; only
IPPS rasters can be converted.
Some dumpf volumes are written on more than one tape. Task rdumpf cannot recover a file that is split across two tapes on a "multi-volume-set" dumpf tape. It is, however, possible to read the files beyond the leading partial file; this is done by incrementing the file_list parameter by 1. For example, the first complete file on the second tape of a multi-volume-set is indicated by file_list = 2.
 Convert all rasters in the 3rd permanent file on tape:
cl> rdumpf mta 3 ipps
 Convert all rasters in all permanent files:
cl> rdumpf mta 1-999 ipps
 List the first 10 IPPS rasters of the first permanent file:
cl> rdumpf mta 1 raster_list=1-10 make_image=no
The Cyber format readers, including rdumpf , have not been implemented on SUN/IRAF and AOS/IRAF.
The current version of IRAF magtape I/O does not read beyond the first
volume of a multivolume tape. As described above, rdumpf
read a file split across two tapes.
The record structure of a DUMPF tape is used to filter out noise records and extraneous bits that fill out a tape byte; this tape structure information is lost when the tape is copied to disk, and so rdumpf may not be able to convert some DUMPF format disk files.
