2018-01-30	Satoshi	CMOS camera settings	I prepared for setups of CMOS cameras and finished 56 cameras.
2018-01-29	Satoshi	CMOS camera settings	I fixed the measures of iris and focus of the CMOS lens with orange LED 28 m away. I installed a software of IP address configuration for the cameras and tried with some cameras.
2018-01-26	Martin, Satoshi	IF plate assembly	We replaced wrong-positioned watertight belts with new ones and adjusted vertically the actuators which have >5 mm error (in total 8). We did the same adjustment to the actuators whose watertight belts were slipped off by mistake (in total 3).
2018-01-25	Martin, Satoshi	IF plate assembly	We tried to replace watertight belts of actuators with new ones from MAGIC experiment. Satoshi broke a new one while screwing. We learned how strongly we fix the belts.
2018-01-24	Koji, Satoshi, Tomohiro	IF plate labeling	We attached coordinate-labels on all the completed plates.
2018-01-23	Martin, Koji, Satoshi, Tomohiro	IF plate assembly	We finished attaching actuators to 42 plates. (in total 180 completed). We finished all the ordinary IF plates except the ones on edges.
2018-01-22	Martin, Koji, Satoshi, Tomohiro	IF plate assembly	We finished attaching actuators to 86 plates. (in total 138 completed).
2018-01-21	Koji, Satoshi, Tomohiro	IF plate assembly	We finished attaching actuators to 18 plates. (in total 52 completed) We stored completed IF plates so that their positions correspond to the ones in the dish structure of the telescope.
2018-01-19	Martin, Satoshi, Tomohiro	IF plate assembly	We confirmed how to adjust fixed points horizontally (with a caliper Martin bought today). We finished attaching actuators to 14 plates. (in total 34 completed) We cannot fix actuator covers as they have not arrived in Mirca yet. We also received all the threaded 700 pins we ordered last week.
2018-01-18	Martin, Satoshi, Tomohiro	IF plate assembly	We finished attaching tube spacers on 30 plates. (in total 20 completed & 160 tube spacer attached) We stopped attaching them as the total number reached 180, enough for ordinary IF plates.
2018-01-17	Martin, Satoshi, Tomohiro	IF plate assembly	We finished attaching tube spacers on 30 plates. (in total 20 completed & 130 tube spacer attached) Eduardo brought 150 threaded pins to Mirca.
2018-01-16	Martin, Satoshi, Tomohiro	IF plate assembly	We finished attaching tube spacers on 35 plates. (in total 20 completed & 100 tube spacer attached)
2018-01-15	Martin, Satoshi, Tomohiro	IF plate assembly	We finished attaching tube spacers on 36 plates. (in total 20 completed & 65 tube spacer attached)
2018-01-14	Satoshi, Tomohiro	IF plate assembly	We finished attaching tube spacers on 19 plates. (in total 20 completed & 29 tube spacer attached)
2018-01-12	Martin, Satoshi, Tomohiro	IF plate assembly	We completed 11 plates and finished attaching tube spacers on 10 plates. (in total 20 completed & 10 tube spacer attached)
2018-01-11	Martin, Satoshi, Tomohiro	preparation for IF plate assembly	We removed 351 unnecessary aluminum plates from actuators and 700 small pins to be threaded. We also confirmed how to assemble IF plates and completed 2 plates additionally (in total 9 completed).
2018-01-10	Satoshi, Tomohiro	arrival in La Palma

Tips

- Some of actuators have watertight belts so far from their tops that IF plates cannot be adjusted to the right positions vertically. We found 4 with ~5 mm displacement out of 52 so far. We may have to replace the belts with new ones (Martin said there are belts fixing with screwing here in La Palma.)

- Bolts for fixing tube spacers have square shapes under their hats. Some of the square shapes are tight and difficult to slide smoothly. We might not use them.
