imexamine errorStarted by:Guest, 10/26/2005 05:48PM
Hi Terry,
The message is coming from DS9 itself
and we have no other
report of this, so you might also ask at
saord@cfa.harvard.edu to
see whether they know what's going on.
It sounds as though there
is some confusion about the display
frame so you m...

Good morning,

I am Paola Rodriguez Hidalgo, a
graduate student from UF. I am
experimenting problems when using the
task "apall" to extract spectra
from 2D images. Sometimes a weird "bump"
shows up in the spectra. It

imstatistics significant figuresStarted by:Guest, 10/20/2005 09:22PM
Hi John,
By default the output is printed using
a '%10.4g' format, but if
you turn off the 'format' parameter to
print the column headings a more
general '%g' format is used and you'll
see the extra precision.
Otherwise, a code change is required to

imstatistics significant figuresStarted by:Guest, 10/20/2005 05:29AM
Hello -

The imstat results produce (e.g. for
mean) four
significant figures (e.g. 110.1 or
99.91). Is there
an easy way to get 5 significant figures
to appear
(e.g. 110.17), perhaps an analog to
imstatistics?

thanks

Venkat,
The Sun rasterfile format has an
assumed byte order. I'm
guessing you're running this on a linux
PC of some kind? If so
you can correct the file for the local
byte order using the REBLOCK
