A blog about a system to determine terrestrial albedo by earthshine observations. Feasible thanks to sheer determination.

More small steps

Got the FWs moving today, using very basic LabView modules. Engineering Mode does not seem to want to talk to its 'subVIs' any more.

For reference:

in the VI 'set DO line' you can select port and line combinations. So far we know that:

port0/line22 operates the realys in the Breakout Box labelled RE2 and RE4.
port0/line23 - RE3 och RE5
port0/line20 controls the Thor FWs. The two relays adjacent to the Thor controllers come alive. The FW can be selected via the pushbuttons on the boxes.

If we can get the camera alive next we could at the very least do lab work on the CCD properties - make color flat fields, study the PSF in various filters, and so on.
