MIPS Critical Tasks Aug. 21, 2003 ================================= The tasks summarized here are 'critical' in one or more of two senses: 1) They are necessary to show that MIPS satisfies the Level 1 requirements. 2) They require fast data processing, analysis, and response to the project. 3) They are verifications of such basic instrument operations that a failure in one of them will likely require significant replannin of MIPS IOC activities and/or operations. The 'critical' classification is intende to help us track the most important things going on in IOC. Failure of a 'critical' task is NOT intended to automatically trigger any particular response except that the IOC team needs to THINK about the appropriate response. The list of critical tasks was determined by melding: Quick Turnaround Events (IOC Walkthrough, April 7 2003, see JAS email of 4/3/2003) these were mostly picked out by George Global Critical Tasks (IOC Cogs mtg, May 21 2003, see JAS email that date) Global Critcals: Critical tasks are those which would, on failure, have such far-reaching impacts that they needn't be specifically cited as dependencies for other tasks. The ones we identified fall into 4 categories: Hardware Anomaly mips-10, 15, 900, 990 basic CE and mips aliveness, functionality mips-115, 247, 248 stim operability, brightness noise-related tasks: mips-15 csmm jitter, 160eng. px. noise, 70 bad readout ramps mips-910, 950 24um readnoise mips-125 24um data ramps mips-950 70um ramps (camp. F), 160um ramps (camp. G) mips-911, 912 Ge readnoise, dark current mips-92 CE temperature monitoring *mips-245, 246 Array Biases Telesope Cooling Anomaly MIPS-C thermal balance basic check on observatory thermal balance mips-950 thermal background levels check mips-10 mips/CE termperatures Pointing Anomaly IRAC 1st lights early sign if frame tables are OK in general mips-100, 322, 324, *300 1st light - is pointing even close to correct? Commanding Anomaly This is a big area, and very hard to track with 'dependencies'. Early tests should give us confidence that uploads are accurate and getting to the S/C in one piece, and that downlinks are getting processed accurately and completely. One specific dependency ID'd: mips-100 is CSMM motion sense/scale correct? Dump of critical tasks in IOC_DB (8/21/03): ------------------------------------------- In general the first few occurrences of a critical or a quick-turnaround task where assigned a priority of 'critical' in the ioc database. Those assignments may need to be refined as IOC progresses. Nothing in SV was given a priority of 'critical'. mysql> select caid, campn0, title from ioc_tasks where ioc_pri='critical' order by caid, campn0; +------+--------+---------------------------------------------------------+ | caid | campn0 | title | +------+--------+---------------------------------------------------------+ | 10 | A1 | Start-up Activities, Si | | 15 | A1 | CE State Validation & Functional Tests | | 92 | A1 | Campaign A Temperature Monitoring | | 100 | D1 | 24 um first light | | 115 | D1 | 24 um Detector Response to Stims | | 121 | D2 | 24 um Focus Confirmation | | 121 | E | 24 um Focus Confirmation | | 121 | F | 24 um Focus Confirmation | | 125 | D1 | 24 um Voffset Adjustment Test | | 130 | F | 24 um Focal Plane Survey (Coarse) | | 130 | G | 24 um Focal Plane Survey (Coarse) | | 132 | H | 70 um WF Focal Plane Survey (Coarse) | | 137 | I | 70 um NF Focal Plane Survey (Coarse) | | 139 | I | SED slit location and orientation | | 234 | J | 160 um Array Location and Orientation | | 245 | F | 24 um Optimum Bias Setting | | 246 | I | 70 um and 160 um Optimum Bias Setting | | 247 | G | 70 um stim response | | 248 | H | 160 um stim response | | 300 | K | SED Skeleton AOT Validation | | 322 | G | 70 um first light and Ph/SR AOT Validation - preliminar | | 324 | H | 160 um first light and Ph/SR AOT Validation - prelimina | | 326 | H | 24 um Scan AOT Validation - preliminary | | 900 | B | Start-up Activities, Si | | 900 | C1 | Start-up Activities, Si | | 905 | G | Start-up Activities, Si & Ge | | 905 | H | Start-up Activities, Si & Ge | | 910 | D2 | IOC Darks, 24 um | | 910 | E | IOC Darks, 24 um | | 911 | G | IOC Darks - 70 um | | 911 | H | IOC Darks - 70 um | | 911 | I | IOC Darks - 70 um | | 912 | H | IOC Darks, 160 um | | 912 | J | IOC Darks, 160 um | | 912 | K | IOC Darks, 160 um | | 950 | A1 | Scattered Background Monitor | | 950 | B | Scattered Background Monitor | | 950 | C1 | Scattered Background Monitor | | 950 | D1 | Scattered Background Monitor | | 990 | B | Shut-down Activities, Si only | | 990 | C2 | Shut-down Activities, Si only | | 992 | G | Shut-down Activities, Ge (& Si) | | 992 | H | Shut-down Activities, Ge (& Si) | +------+--------+---------------------------------------------------------+ 43 rows in set
