Main Menu

The options in the main menu are as follows:

RESULTS

Display a plane of the results block. The plane is accessed by name, and this is one of only two places in the whole of Twodspec that cares about the case of the answer given by the user (the other is MODPARAMS). For example, if you wanted to display the centre of the first component, you would enter ``Centre_1''.

DATA

Display a plane of the data

PROFILE

Examine line profiles. The profiles are selected using a cursor. If more than one is selected they are added together. Gaussians etc. may be fitted to the profile, and the results stored. The fitting is similar to that of LONGSLIT. Hard-copy plots of the profile may also be made.

XCUT

Take a cut through the data in the X direction, and display on a greyscale device. The position is marked with a cursor, and the nearest pixels are chosen (i.e. no interpolation).

YCUT

Take a cut through the data in the Y direction, and display on a greyscale device. Similar to XCUT.

XOUT

Output to file X direction cut through data. This is like XCUT, but the output is to a file, rather than an image display.

YOUT

Output to file Y direction cut through data. Similar to YOUT.

IT

Reduce iteration

CHECK

Display an array of line profiles--this can be in soft or hard-copy

TOTAL

Display the summed intensity through the image

LIMIT

Limit X and Y range for display. This acts as a toggle, so if you have limited plots and select this option again, you will return to full range.

TOLS

Apply/set tolerances

LOOK

Look at values in results cube

DELETE

Delete fits from results cube

DEFINE

Define fits for batch mode. The fits are defined and stored in the control array.

OUTPUT

This allows the user to list all the fits onto the line printer, or to produce hardcopy plots of all the fits.

EXIT

Leave the program

CUBAN

Cuban-style display/motion. This is better than CHECK for large data-sets (such as from TAURUS). An array of profiles is plotted, with a small greyscale representation of the total intensity in the top right-hand corner--the centre of the array plot is marked on this with a cross. The user has the following options (decided by cursor keys):

A

Add profiles to fit (end with F)

C

Centre here

D

Down

E

Exit

F

Make fit to point

H

Make hardcopy of current plot

J

Jump to new area (using greyscale plot)

L

Left

P

Indicate position

R

Right

S

Set scaling for profile plots

U

Up

X

Erase fit

Help

Note that the following options require the use of a greyscale display: RESULTS; DATA; XCUT; YCUT and TOTAL, although PGPLOT is capable of producing a simulated greyscale on line graphics devices, if the array is rectangular.
