BTC and BTW?

A friend of mine asked this question, and I didn't know the answer.. On her light plot, a couple instruments have either BTC or BTW for the focus area. Any ideas what either abbreviation stands for? The instruments are on the first electric in a high school auditorium. Thanks in advance!

BeTween Warm (R17) and BeTween Cool (R54) ?
 
Behind the Wall , Behind the Curtain?

Can we see the whole plot?
 
The 50°'s probably throw such a wide pool they don't fit into the standard circles. Probably just fill in upstage whatever the catwalk or front of house lighting can't hit or back light for the apron. Maybe "Back T____ Warm/Cool"?

Might also be some reference to a specific show or event setup where they bring in risers or have the band on-stage.
 
My God Man! Trim the hair on your Knuckles !
 
Based on some of the other fixtures, it looks like it denotes the system or zone it is for. I think Derek's on the right path with warm/cool differentiation but the BT part is ambiguous and likely something upstage.
 
Thanks for the theories. Not sure if this will help, but this plot was the original plot from when the school and theater were constructed and outfitted about 12 years ago. I don't believe that any lighting designers have ever worked in the theater or created a different plot.
 
Someone please tell the designer her instrument numbers are backwards. While there's often debate about whether area One is DSL or DSR (depending almost solely on the age of the designer [or his/her mentor]), unit numbers always start with #1 SL. Yes, it's antiquated, and comes from a time when control was located backstage, but that's just how it is.

Our stage was renovated in 2010, and the all new lighting system is numbered from SR to SL... Perhaps not as much a standard anymore?

Boo! Hiss!! Excuse me while I try not to throw up!!!
Did someone let the IBEW number your circuits for you?
Until my retirement, my IBEW brothers would have done that and thought themselves neatly organized.
Toodleoo!

SL to SR was fine when lights were run on old resistance or autotransformer boards from backstage. Time has moved on. Boards are now from a house position. I guess when you are mounting the plot, you are working from the stage, so it has it's merits.

Time to start putting dark grey circuit numbers on the downstage faces of electrics?

And terminating the cables with Socapex, or equivalent, 6 circuit mults and Pyle-National, or equivalent, 12 circuit mults. Possibly having pre-labelled circuit boxes oriented with clamps on the bottom spaced above the pipes enough that fixtures hung below the pipes could clamp below the boxes having your dark grey numerals oriented to be easily read from that orientation. Possibly label the boxes on both U/S and D/S surfaces. Next thing consultants are going to "invent" U shaped cable supports with clamps on the bottoms which could be clamped anywhere along fly pipes and cables simply draped into the U's and have a tie-line or Velcro wrap added before the pipe is flown to trim. Anything that can be done to speed and simplify cable management and handling is time well spent, even more so if it's reducing unionized labor costs.
(I may get to like you yet @MNicolai . Possibly if you grew a beard and kept it neatly trimmed??)

If there is a user who is concerned, I ask. Professional houses, colleges with current staff, even high schools where there is someone who knows a little about lighting. heck, if they want P and OP and RGB labels, I might try to dissuade them but they have to work there. A college or high school with no staff beyond an english teacher and band director, where they probably won't move a fixture more than a couple once a year at most - number it so they can read left to right from the control room. Why one solution has to be applied tio all - and an already noted antiquated one - is beyond me.

Back when I learned lighting and mind you this was the rock side of things, fixture one was the upstage right fixture, which was also it's dimmer number and it's channel number. 0-10 volt control on a Cinch-Jones connector didn't lend itself to patching so we numbered left to right as we saw it from the board. Upstage lights were always the lower number lights so you could tap out the flashing lights with your left hand on the bump buttons. To this day fixture one on a pipe is stage right on every plot I do.

Now get off my lawn.

Back when I was Head Of Sound in the Stratford Shakespearean Festival's main stage and Bill's parents were driving him up to Ontario to watch theater, we used to have a branch of "Theatre Books", a Toronto based store operated by Leonard McHardy and a partner, in our main lobby. Leonard was a Stratford staff member at the time. I've digressed. I used to regularly peruse the book selection in the the lobby and was amazed to find an entire, hard cover, book devoted to numbering schemes for stage lighting systems in every conceivable manner of venue layout you could imagine. Since I'm no longer permitted to live in my own home, I've began giving away the bulk of my books and I suspect that rarity's among the casualties. I can vaguely recall the physical shape and dimensions of the publication but I've no memory of the author who was likely some nutty professor. I am thrilled to see another of my Stratford cohorts on staff at Yale and looking lovely as ever. Anne Trites must have one of Dorian Gray's (Sp?) photos hidden in her basement. Someday I'll bore folks with why Anne was always referred to as Aunty Em.
Toodleoo!
