yesterdays problems were related to the air
control processes of the telescope - problem solved
(hopefully....) residual effect in the pointing were
noticed in heterodyn observations
(large offset from p-model in az, but stable pointing)
last recycling this afternoon
2263 04 01 22 23 bolotip cal bt 2 46 53 250 0.579 Delta P4, P5:  1.02  3.65
2264/68 04 07 MARS cal p p p f o 2 46 53 251 23 -11.44 -24.04 -3.05 again difficulties to find pointing low counts DataBase flux: 22%
2269 04 21 W3OH cal p p f o 10 46 53 333 59 -16.78 -16.08 -3.37 nic flux much to low... DB reducion 25%
2273 04 33 bolotip cal bt 10 331 0.641 Antenna temperature control seems to be ok
2274 04 39 NGC7538 cal p f f o 10 46 53 324 35 -13.48 -14.07  -3.84 focus driftis like crazy.... DB reduction: 25%
reapply heat pulse 
2281 05 34 bolotip cal bt 326 bad fit - invers curvature - bolometer still unstable???
sky cloudy by now
2282 05 46 W3OH cal p f f o 10 46 53 325 50 -16.89 -7.24 -4.07 pointing looks ok... 25%
2286 05 53 bolotip cal bt 324 now curvature is correct but fit still bad 
individual subscans still show instabilities
2287 06 13 bolotip bt 325 0.505 ok
2288 06 20 W3OH cal p f o 10 46 53 324 46 -15.40 -8.56 -4.04 focus has stabillized
30%

Aborber maps ... look ok...

2301 07 48 SATURN p f  f /dir x,y  twice each 2 42 53 226 70 -24.37 -13.53  -4.14 measure lateral focus
getting an error from  temperature control
2306 08 09 J0739+016 p f   10 42 53 192 53 too weak for lateral focus (with current system...)
2309 08 18 JUPITER 2 42 53 116 38 to big

2325/28 09 27 CW-LEO p p f o 10 46 53 167 65 -21.20 -9.40 35% give up .....
Heterodyn measurement clearly prove, that
these problems are related to surface deformations
caused by a failture of the backstructure temperature control
