VIEW/IMAGE [frame] [out_tab] [plot_option] [g,zhardcopy]

view an image with a "looking glass"
19
View an image with a "looking glass" and get statistics.
22
VIEW/IMAGE [frame] [out_tab] [plot_option] [g,zhardcopy]
24
frame = name of image, the image will be loaded with the cuts set
25
to mean-3*sigma, mean+3*sigma
26
if omitted, the currently displayed image is used
28
out_tab = name of optional output table for coordinates of visited
31
plot_option = P or N, for P(lotting) or N(oPlotting), defaulted to P;
33
g,zhardcopy = names of plotters for hardcopies of graphics window
34
(initiated via key `p') and zoom window (initiated via key `q');
35
defaulted to LASER,LASER
38

42
If the zoom window does not exist yet, it will be created with
43
half the size in x and y of main display window.
44
Also a graphics window will be opened. And, finally, a separate
45
terminal window is used for the additional output (which is not
46
stored in the Midas logfile).
47
Use the cursor to select the center of subimages to be viewed.
48
These subimages are zoomed according to the current zoom factor
49
and displayed in the zoom_window.
50
This command has lots of different options which are activated
51
via different keys on the keyboard. But note, that the cursor has
52
to remain in the display window at all times, even if you type on
54
The available options are obtained by entering 'h'.
55
The optional output table will have columns with the standard
56
labels :XSTART, :YSTART, :XEND and :YEND.
57
If the plotting option is set to row/column-trace mode, not
58
the 2-dim region of interest is extracted with the `e' command,
59
but the row or column at the center (the one which is plotted).
64
Load image `cielo.bdf' with low, high cut values set to
65
mean-3*sigma and mean+3*sigma.
66
Use the default size (or size of existing auxiliary window) for
69
VIEW/IMAGE cielo ? ? ps4ipg1
70
As above, but send all eventual hardcopies to printer with the
74
Work on image which is currently loaded in the display, write the
75
coordinates of all regions which were visited into output table
78
VIEW/IMAGE estrella.mt
79
The FITS file `estrella.mt' is loaded into the display window and
80
worked on like any binary Midas frame.
