CREATE/STAR in_frm in_tab out_frm [n_size] [frm_specs] [dmin,dmax] [radius]
16
create the profile of a reference star by adding and averaging
19
Create a frame containing the profile of the standard reference
20
star, by adding and averaging inside a circular window some
21
selected stars, after recentering
24
CREATE/STAR in_frame in_table out_frame [n_size] [frm_specs]
27
in_frame = input frame containing the selected stars
29
in_table = input table containing the coordinates of
30
these stars in column :X_COORD and :Y_COORD
32
out_frame = output frame containing the calculated reference
35
n_size = size of the output frame in number of pixels. The
36
output frame will square, having n_size pixels in
39
frm_specs = specifications for the output frame in the format
40
startx, starty, stepx, stepy. Default are the values
43
dmin,dmax = low cut, high cut to select the stars; defaulted to
44
the real cuts of the input frame
46
radius = in pixel number, the radius of a circular window
47
centered on each selected star; default 20
50
The input table containing the input star coordinates can easily
51
obtained by the command GET/CURSOR.\\
53
The maximum of the stellar profile will be in the centre of the
58
crea/star tspiral ttab ttest 128 0,0,0.1,0.1 ? 40
59
Create a frame of 128 * 128 pixels containing the stellar profile
60
obtained by averaging the stars stored in tabel `ttab'. The input
61
frame is `tspiral'. The default for the low and high cuts is to
62
be used; the radius of the circular window is 40 pixels.
