Problems with Pyro and interferometerctrl, fixed by restarting adsecsx software

Problem with get_m4d: the system does not like the name file "hex". routine modified, new name file ="hexa"

guess on the convection issue

J Carlos suggests that the convection source is the dome wall. the wall, closest to the adsecsx, is east, so during the morning hot air will blow from that wall.

a test of this assumption is to identify the direction of the flow. this was measured with a 4D burst and we found that the bubbles are moving along the linecrate 1/crate 4 (we don't know the direction). this line corresponds to SouthEast-NorthWest (measured at midday, sun at south..)

we measure the temperatures in the chamber and found a vertical gradient of 1° (13.6 to 14.6) in the walls east ans southeast and no gradient in walls south west and west. walls north have a negative gradient (warmer down).

tomorrow we will ask to have the dome 180° rotated
