mscan -- Read sector scans from tape into IRAF images
- File template or device, e.g. "junk" or "s*" or "mta1600" or "mtb800"
- List of tape file numbers or ranges delimited by commas, e.g. "1-3,5-8". `Files' is requested only if no file number is given in `input' and the input is tape. Files will be read in ascending order, regardless of the order of the list. Reading will terminate if EOT is reached, thus a list such as "1-999" may be used to read all the files on the tape.
- verbose = yes
- Flag to signal program that it should produce verbose output. This means header information.
- makeimage = yes
- Flag to signal the program that it should make images. If this parameter is set to no, the header will be read and decoded but no data will be read and no image will be produced on disk.
- brief = yes
- Flag to make mscan produce brief filenames for the output images. These filenames have the form [svb]nnn e.g. s034 or b122. The b is for a brightness image, the v is for a velocity image, and the s is for a select image. The nnn is the tape sequence number or the filenumber in a template expansion. If this flag is set to false the long filenames described below in the 'Description" section will be produced.
- select = yes
- Flag to tell the program to make a select image.
- bright = yes
- Flag to tell the program to make a brightness image.
- velocity = yes
- Flag to tell the program to make a velocity image.
The first letter is one of [bsv] for brightness, select, or velocity. The next two digits are the day of the month. Underbar. The next 4 digits are the hour and minute. Underbar. Finally there is a three digit tape sequence number. ie. b13_1709_002
1. To read files 5-7 from mta at 1600 bpi, the command would be:
vt> mscan mta1600 5-7
2. To see the header information only for file 6, one could use the command:
vt> mscan mta1600 make-
3. To read file 4 from mta and only produce a velocity image:
vt> mscan mta bri- sel-
