Night: 19-20 September 2002 Observer: Giovanni Covone Operator: Juan Carlos Guerra Program: McMahon (spectroscopy of z~2 quasars) ------------------------------- (this is a rough lig-file taken during the night, with some later notes) (I think it will be useful) ------------------------------- Time: 20:10 (local time). Humidity: more than 80% Nics temperature: 84K Lamps on, motors ok. No problems with Xnics (NICS user interface). Single image to check the system: Message form Xnics: "task cannot be executed. No open link to TNX." Let's try again: Exit from Xnics. Transputers do not boot. Try again. Startup ok. Single image to check the system: some problems, it's stuck. Stop image acquisition. Exit Xnics. Transputers do not boot. Exit Xnics. Startup ok. Free run to check the system: form the system (cut & paste): *NICSgate: ReadFromTNX: - : integration completed ! - *NICSgate: ReadFromTNX: Frame transmition is started something did not work Exit Xnics I switch off the electronics Startup ok. Single frame: ok! Frame: frdz0001, test frame.

Clear array We start with the highest priority object. Altitude: 31 degrees. ------------------------------ B1649+5302 ------------------------------ setup imaging: SW filter, in order to have more photons frdz0019 filter SW, exp=30 s: not good! what happened: condensation of water? Clear array frdz0020 filter SW, exp=30 s Diffusor OFF Problems with transupers: start Xnics again Startup ok frdz0020 filter SW, exp=30 s still some water give a small offset frdz0021 filter SW, exp=30 s move object to slit y=650 in order to stay away from the strange water images frdz0022 filter SW, exp=30 s again move to slit frdz0023 filter SW, exp=30 s small offset towards the slit frdz0024 filter SW, exp=30 s ok!

We open around midnight. Considering the weather conditions and priority I decide to continue this program till 4am (local time). Then we continue the other programs (Licandro, Nagar). Other notes: we had some problems at the startup with Xnics (user interface). Reset several times. Some problems with the slit position. For any problems: covone@tng.iac.es
