JBO Radio Imaging Spring School

See computing sheet in imformation pack for details of computing at
JBO. This describes the 'portable' aspects of computing scripts.

Data and scripts are provided for:
(1) MERLIN continuum data
(2) MERLIN spectral line data
(3) VLBI continuum data

Two sorts of runfile are provided. Firstly DEMOS, in these you run
the script and then press return to see the data processing take place
with a commentary; secondly conventional RUNFILES which you can use as
templates for a typical data processing session.

DEMOS

FLOWCHARTS and PLOTS are available on the web, and the runfiles.

MERLIN CONTINUUM

BASIC.EHEX 	requires 95apr18.d:2.FITS plots BPL.*
GENCAL.EHEX	requires 3C277.1.MULTFG	  plots GPL.*	
SELFCAL.EHEX	requires 3C277.1.MULTC1	  plots SPL.*	
IMAGE.EHEX	requires 3C277.1.WTMOD	  plots IPL.*

MERLIN OH SPECTRAL LINE

LINE1.EHEX	requires RTVIR_65.MULTTB  plots LPL.*
			 1258+087.IBEM   
			 1258+087.ICLN   
			 44.LCLN         
			 44.RCLN         
			 44.ICLN.1       
			 44.ICLN.2       
			 RTVIR_65.IGEO   
			 RTVIR_65.VGEO   
(as the reduction of mult-channel data takes longer, ready-made
files are provided for this demo).

For the School, the runfiles are in /home/school/SCRIPTS and the data
is in /home/school/DATA - see school computing notes in information
pack.

VLBI CONTINUUM

VLBDEMO.EHEX    requires VLBDEMO.UVDATA
                         VLBDEMO.TASAV

Copy VLBDEMO.EHEX, rename it and setenv RUNFIL to your directory as
for any other runfile (see computing notes in information pack).
At the School, the uv data for the VLBI demo is loaded onto the
scratch disks of the machines available for vlbi, eg aetna, so
% setenv WORK /scratch/aetna_1 
(or whatever your machine is called).

To run the scripts from your home institute:
Download the .EHEX file you want and copy it to .XXX
where XXX is your AIPS number in ehex (3 digits).

Download the required data.

If these are in directory home/aips then

% setenv RUNFIL home/aips
% setenv WORK   home/aips
% setenv PRINT   home/aips
% aips new
where this is the 15OCT99 version of aips, some modifications may be
needed to run under other versions.

To run a demo, eg BASIC, type
> run BASIC
which loads the procedure, then
> BASIC
to run it.  Keep pressing return every time it stops until it finishes.

If you want to review a plot, find the file it is attatched to, select
> PLVER 2 
(or whatever) and
> go TKPL

To review the inputs the last time a task was run eg IMAGR
> TGET IMAGR

To see how a task was run on a particular file (all times)
eg CALIB on 33277.1.MULTTB
> PCAT
> getn 1
> PRTASK 'CALIB'
> DOCRT 1
> go PRTHI

After each demo has finished delete all files in your AIPS number
before you run the next one.

RUNFILES

These are a series of runfiles covering successive stages of data
reduction.  You can run them sequentially, each file stops when you
have to do something eg edit by hand, or you can read them and make
more substantial edits or enter the commands you want by hand using
the runfiles as a guide.

For the School, these are in 
/home/school/SCRIPTS
and the data is in
/home/school/DATA

MERLIN CONTINUUM

RUN_C?.EHEX are files for processing 3C277.1 from 95apr18.d:2.FITS and
schedit? are scripts for automatic minor customisation (eg to disk
No., refant).

RUN-??.EHEX are files for processing any similar data (RUN-C?.EHEX is
 for a pointlike ph-ref source; if the ph-ref is resolved RUN-R2.EHEX,
 RUN-R3.EHEX replace two of the RUN-C?.EHEX files).  redit? are
 scripts for automatic minor customisation (eg to disk No., refant,
 source names).

MERLIN LINE

LINE-?.EHEX are for processing RT Vir OH data, requiring
93dec10.d:2.FITS_60  93dec10.d:2.FITS_65  93dec10.d:2.FITS_67.
LINE-end.EHEX is guidelines for the final stages.  
Read the preamble and comments to each runfile.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

If you want to run these at your home institute 3C277.1RUN.tar.Z
contains RUN_C?.EHEX for processing 3C277.1 from 95apr18.d:2.FITS and
CONTINUUMRUN.tar.Z is RUN-??.EHEX for any similar data.

LINERUN.tar.Z contains LINE-?.EHEX

Download the files as described later on the School page, gunzip and
extract them eg
% gunzip CONTINUUMRUN.tar
% tar xvf  CONTINUUMRUN.tar
%chmod u+rwx redit?

You need to get the data separately eg from the ftp area.

Read the preamble in each runfile and follow instructions. Do not delete 
the files (especially uv data) until you have finished the whole set.
They are designed to run using the October 99 version of AIPS, some
changes may be needed for other versions.

Start aips as above eg
% setenv RUNFIL home/aips
% setenv WORK   home/aips
% setenv PRINT   home/aips
% aips new
