Brian,

OK, so the code sent out in the SSEC distribution still contains the
support for the ANNOT= keyword.  I couldn't remember if it did or not.
At one point in the past (after SSEC adopted BAR) I do remember that I
had to add the support back in.

The time(s) is(are) only displayed for precip. products.

Right.  That was my rationale.

So, you guys don't like the black background in the BREF enhancement
either!?  Russ agrees with you.  The enhancement that he likes uses a
gray color for the background.

Another comment.  I seem to always load the NIDS images centered on the
station that is being loaded:

IMGDISP NEXRAD/BREF1 ID=LCH STA=LCH EU=BREF REFRESH='EG;MAP H;BAR ANNOT=YES'

>The image looks good!

>Just curious why the time didn't show up for the
>ANNOT=YES part though?  No biggie.

The only products that get a time added with the ANNOT= keyword are the
precipitation ones (1-hour, 3-hour, and storm total).  The reason for
this is that the time of all other images is what is returned back in
the synthesized AREA header.  The precipitation products, on the other
hand have a second or, in the case of storm total precip., third
associated time.  The second time for the 1 and 3 hour precip. products
is the ending time for the sampling.  The second and third times for
the storm total precip. product are the beginning and ending times
represented by the product.

>Thanks for your help as always!

You are welcome.  I am still curious about what parts of the annotation
included in the examples you sent previously are important.  I chose
to make the annotations terse in order to conserve on display space.
For users running with 480x640 image windows, there is not a whole lot
of space for annotations IF the objective is to not cover up the 
display itself.
