Dear colleagues-

Just a quick note on SPIcam. The default binning is 2 x 2, 
which gives a plate scale of (2x0.14) ~ 0.28 arcsec effective
pixels.

We're been running a program that requires short exposures and
have been running the camera binned 3 x 3 for (3x0.14)~0.42 arcsec
pixels. THe readout time is considerably shorter and sampling is
good enough.

To run in this mode, type 

rebin 3 3

at the spicam promopt.

Of course, you'll need flats in this mode as well..
