Initial script help

initial.csh RAWDIR ROR ROOT BGRADIN BGRADOUT RA DEC

RAWDIR = working directory e.g. /exgal2/sfh/temp
ROR = ROR description of downloaded data e.g. rp600005n00
ROOT = a name you pick. Many file names will begin with this e.g. ngc720
BGRADIN = inner radius of background annulus e.g. 0.6
BGRADOUT = outer radius of background annulus e.g. 0.7
RA = ra of object in degrees (J2000) e.g. 28.23
DEC = dec of object in degrees (J2000) e.g. -17.0

N.B. the RA and DEC expect a decimal point to be included.
i.e. type 23.0 not 23

The following files will need to be present when this script is run:

default.set     sets up some values such as resolution of spectral and
                spatial bins. If you want to use different values than this
                file gives type: source default.set . This will create a
                file called defaults.txt which can be edited. (or you could
                just alter the default.set file which the script will call
                later - usefull if you want to regularly use different
                values to those I use)
pkstart         starts up asterix, obelix, kappa (Also sets up a variable
                $fstart to start up ftools if it is needed) as appropriate
                for your computer. Also creates a variable $mach which
                tells the script what computer it is being run on
                (sun,linux,etc)
extra           use to add extra ignores. Usefull if a large diffuse source
                is sitting in your background annulus.

This script is designed to carry out initial reduction. It will generate
the following files.

ROOT_cube_broad.sdf     raw data cube (x,y,E)
ROOT_bcube_broad.sdf    cube containing background annulus
ROOT_bmcube_broad.sdf   cube containing background model
ROOT_bscube_broad.sdf   background subtracted cube
ROOT_ccube_broad.sdf    bg subtracted and corrected cube (xrtcorr)
ROOT_bimage.sdf         image of background model
ROOT_bimage_1_p.sdf     polar profile of above file centered on specified
                        position
ROOT_image.sdf          image of raw data
ROOT_image_1_p.sdf      polar profile of above file centered on specified
                        position
ROOT_cimage.sdf         image of subtracted and corrected data
ROOT_src_broad.pss      text file - output from pss
ROOT_src_broad.sdf      output from pss in sdf format
ROOT_sigmap_broad.sdf   signifcance map produced by pss
ROOT_rate_ok_1.lis      a list of good time slots
ard_broad.dat           ard file containing pt. sources and support   
                        structure.
profile.sdf             polar profile showing raw data divided by
                        background as a function of radius
stored.txt              contains contains position (derived from RA and
                        DEC) in image coordinates

Rough procedure.

1) Unpack data (gunzip,tar,uncompress)
2) Get good time periods
3) sort cube
4) create background cube with annulus
5) background subtract data and create background model
6) project to images and source search
7) recreate background cube this time excluding pt sources found in 6)
8) repeat 5), 6), 7) and 8) until same number of sources are found each
   time
9) check that bg model does appear to give a good description of the
   data. Warn if it doesn't.
10)Final bg subtraction. Correct cube (dead time,wires,cnts/sec,etc) and
   attach a spectral response.
11)Create final images. Generate profile.sdf (see above). Clean up.
