[Akutsu, Kokeyama]
TMSX blade moving along the temperature change. The attached plot shows the temperature change of 3.5 deg C (a lot!) and blade tilt change of ~30 urad for 3 days.
Actually it seems the LVDT signals show that the TMS-VIS table has moved about 15urad in yaw, and 30um in vertical along with the temperature change in these 3 days. This effect would be due to the change of the spring constant along with the temperature change; the cooler the room, the stiffer the blades would be.
The most strange thing is that the thermometer showed 29.5 C deg on Oct 9 12:00 UTC (21:00JST), but... I did not remember well but did not feel such high temperature...
