You may have decided to first load your data onto disk outside of AIPS\ and now you want to convert it into AIPS format. You may have done this because you wish to experiment with the many options in ATLOD and it will be faster to read from disk than tape. This is the section for you. You can load the data from disk into AIPS with either the Convex or a workstation depending upon where you have your disk booking (it could be the Convex) and what your needs are. Generally, you will be doing this with a workstation. We encourage you to restrict your use of the Convex to large computational jobs.
where your files are all prefixed by 91-04-23_, say, and suffixed by the the UT (wild-carded with the *). It will save you some trouble later on in AIPS if the concatenated file is in time order. The current file naming convention should ensure this (i.e., the files list in time order when you examine a directory of them with, say, the UNIX command ls), but data from the first half of 1990 may not. If not, then put them all in time order on the command line in the cat operation. For example,
Note that you must make the name of the concatenated file in upper case (here I have called it `BIGFILE') because of the disinterest AIPS shows in lower case. Remember to delete the multiple files, leaving only the concatenated file. Do this with a command such as
Note that this is not the standard Unix lower case command pwd but an ATNF specific upper case one which does not get confused by the automounters. Note also the backwards quotes; you must type these as shown. You can examine the value of `MYAREA' with
and enter your AIPS user number when prompted.
