Among exposures taken at the = same telescope positions, but it was slew away andslew = back, the variation on R1 and R2 are 2000 steps and 315 steps, 2 = degreesand 9 degrees on B1 and B2. Among all exposures in the test, Variation ranges for R1 and = R2 are 3500 stepsand 950 steps, 3 degrees and 10 degrees = for B1 and B2. ---- Weather Log ---- Wind 1 um DIMM IRSCTime Temp = C = Dewp C = MPH = Dir = Dust = fwhm = mean = sigmaN/A---- Telescope Status ----Never opened.No interlocks bypassedStatus at: 11:17ZTelescope = stowed at: 121.0, 30.0, 0.0 mountInstrument mounted: cartridge =3D = 13 Counterweights at: = 437LN2 autofill systems: Connected and turned on180L LN2 dewar scales: SP1 119 = lbs, 20 psi = &n= bsp; SP2 = 101 lbs, 19 psi---- Software Used ---- -- STUI = software: STUI = : 1.7.1b2alerts : = trunk+svn149374apo = : = trunk+svn158476Mboss = : v3_6-boss.specMec : 3.0.4gcamera = : v2_1guider = : v3_3hartmann = : v1_4_3hub = : Tag: = sdss4_v3_0mcp = : v6_6_18-mcp.plc : 31-mcp.azFiduci : v1_118-mcp.altFiduc : = v1_118-mcp.rotFiduc : v1_118platedb = : v2_3sop = : = trunk+svn64851tcc = : 1.2.2apogee : not = availbleapogeecal : not = availbleapogeeql : = v1_6_1APO-local : trunkidlspec2d : = v5_7_12plate-mapper3 : = NOCVS:v6_0_4petunia = : v2_4_1autoscheduler : trunksdss_python_module: v2_1_20mangadrp = : trunk = exportedSetting up: idlspec2d = &n= bsp; Flavor: = Linux64 Version: v5_7_12Setting up: = |elodie = &n= bsp; Flav= or: Linux64 Version: v1_3Setting up: = |spinspect = &n= bsp; Flavor: Linux64 = Version: trunkSetting up: |specflat = &n= bsp; Flavor: = Linux64 Version: v1_20Setting up: = |speclog = &n= bsp; Flavor: = Linux64 Version: trunkSetting up: = |platelist = &n= bsp; Flavor: Linux64 = Version: trunkSetting up: = |sdss_python_module = Fl= avor: Linux64 Version: v1_6_7Setting = up: |sqlalchemy = &n= bsp; Flavor: Linux64 = Version: 0.9.7Setting up: |psycopg2 = &n= bsp; Flavor: = Linux64 Version: 2.5.3Setting up: = |idlutils = &n= bsp; Flavor: = Linux64 Version: v5_5_16Setting up: = |idl = &n= bsp; &nbs= p; Flavor: Linux64 Version: 7.1Setting up: |dust = &n= bsp; &nbs= p; Flavor: Linux64 Version: v0_1Setting up: |photolog = &n= bsp; Flavor: = Linux64 Version: trunkSetting up: = actorcore = &n= bsp; Flavor: = Linux64 Version: v3_2_1Setting up: = |opscore = &n= bsp; Flavor: = Linux64 Version: v2_2Setting up: = |external = &n= bsp; Flavor: = Linux64 Version: v1_2_0Setting up: = |actorkeys = &n= bsp; Flavor: Linux64 = Version: trunkSetting up: |sdss3tools = &n= bsp; Flavor: Linux64 = Version: v1_7_13Setting up: |RO = &n= bsp; &nbs= p; Flavor: Linux64 Version: 3.5.1---- Mirror Numbers ----PRIMARY:--------Scale: = 1.000000;MIGS TONIGHT = NOMINALAxial A: -0.122 -0.118Axial B: 0.123 0.118Axial C: = -0.029 = -0.025Trans D: -1.348 -1.345Lateral E: 10.9601 = 10.9601Lateral F: 12.5984 = 12.5857GALILSCommanded: 11500 -1200 5850 19600 24150 23900Actual: 11500 -1200 5850 19600 24150 = 23900SETMIR VALUESPrimDesOrient: 0.0 -24.21 6.52 356.1 1323.0PrimOrient: 0.0 -24.31 6.14 356.65 = 1322.6SECONDARY:----------Focus: = 0.0000Air temp: = 2.9Altitude: 30.0MIGS = = TONIGHT = NOMINALAxial A: 0.006 0Axial B: = -0.044 = -0.04Axial C: -0.041 -0.041Trans D: -0.009 -0.007GALILSCommanded: 1613300 = 1567800 1570050 -1700 -8100Actual: = 1613299 1567731 1570118 -1700 -8100SETMIR VALUESSecDesOrient: 1257.0 4.35 -15.05 = 25.0 111.05SecOrient: 1256.99 4.31 = -15.05 24.69 110.66PRIMARY:--------Scale: = 1.000000;MIGS TONIGHT = NOMINALAxial A: -0.123 -0.118Axial B: 0.122 0.118Axial C: = -0.028 = -0.025Trans D: -1.347 -1.345Lateral E: 10.9601 = 10.9601Lateral F: 12.5984 = 12.5857GALILSCommanded: 11500 -1200 5850 19600 24150 23900Actual: 11500 -1200 5850 19600 24150 = 23900SETMIR VALUESPrimDesOrient: 0.0 -24.21 6.52 356.1 1323.0PrimOrient: 0.0 -24.31 6.14 356.65 = 1322.6SECONDARY:----------Focus: = 0.0000Air temp: = 3.6Altitude: 30.0MIGS = = TONIGHT = NOMINALAxial A: 0.006 0Axial B: = -0.044 = -0.04Axial C: -0.041 -0.041Trans D: 0 -0.007GALILSCommanded: 1613350 1567800 1570050 -1700 = -8100Actual: 1613350 1567800 1570049 = -1700 -8100SETMIR VALUESSecDesOrient: 1257.0 4.35 -15.05 25.0 111.05SecOrient: 1257.0 4.36 -15.05 24.69 = 110.62____________________________________________________________Logs of Nightly APO Activities https://trac.sdss.org/tracmailman/browser/private/sloan-25mlog/= index.html_________________________________________________________= ___Logs of Nightly APO Activities https://trac.sdss.org/tracmailman/browser/private/sloan-25mlog/= index.html= --Apple-Mail=_41D41E1F-34F7-4C9E-BF3D-160F3823C5B0--
