writevt -- Write vacuum telescope full disk grams to tape
writevt input_image output_fd
- Name of input image.
- File or device name, e.g. "mta1600" or "mtb800" If a file number is not given the user will be asked whether or not this is a new tape. If it is a new tape the file number "1" will be used. If it is not a new tape, i.e. it already has data on it, then file number "EOT" will be used.
- verbose = no
- Flag to signal program that it should produce verbose output. This includes header information and progress reports.
- new_tape = no
- New tape flag. Usage is described above.
Writevt writes a full disk vacuum telescope gram in IRAF image format to tape. The IRAF image is 2048x2048 short integers. The tape format is the same as that used to write original data tapes on the mountain.
1. To write the image "image1" to mta at 1600 bpi at file number 3 and see verbose output the command would be:
vt> writevt image1 mta1600 v+
