Loading the data directly from Exabyte tape into AIPS

 

Here I describe how to read your RPFITS files on an Exabyte tape directly into AIPS.

1. At the UNIX prompt, start up AIPS on the workstation with the lower case command

   aips

   and type in your AIPS user number when prompted.

2. Insert the Exabyte tape into the drive and prepare to select the tape drive in AIPS by setting intape=n, where n is the tape device number. The AIPS tape drive number is written on a label on each Exabyte tape drive. It is usually 1 or 2. Allocate the tape with the AIPS command MOUNT.
3. You can now read the data from tape with the task ATLOD. I will discuss ATLOD in detail in § 4.4. Refer to that section for information on its many inputs. But note here that you should make sure the adverb infile is blank, otherwise ATLOD will look for its input from disk rather than tape.
4. Once ATLOD has run to completion, dismount the tape device with the AIPS command DISMOUNT and collect your Exabyte tape from the tape drive.
