The campaign starts with the standard calibration activities. We need to run the 24um FPS immediately after that, followed by a downlink, to provide the required two days of analysis time for the FPS data. After the downlink, the structure of the rest of the campaign is pretty arbitrary. The latent image study is very important, so I placed that next. A thermal anneal is needed before the start of this task, and another one is needed about halfway through this 5h task. The 24um saturation test is placed next because we will already be pointing towards a region with bright sources, probably at low Galactic latitude. To reduce pointing overheads and as a concession to our star formation crew, I am scheduling the two proto-stellar object observations next. Each is given its own anneal cycle since that is how they are likely to be scheduled in routine ops. MIPS-315 comes next after the proto-stellar objects. It involves observations of standard stars against a variety of backgrounds. It will involve a lot of pointing overheads and will not necessarily start at low Galactic latitude, so placing it here is not necessarily an optimization. One agreement I made with Chad is for him to structure the task so that he doesn't need a thermal anneal in the middle of the task. Most of the rest of the tasks were placed in their own anneal cycle. I did this because we will probably want to look at the 160um data from these tasks and no pair of tasks can be completed within the maximum of 3 hours that we want between 160um anneals. The array geometry task is one of the shortest remaining tasks and it acts as a good spacer to put the 70um dark test a little while after an anneal. MIPS-340 is a 24um task, so there is no problem with placing it next. I placed the 24um PSF task last mostly because it is extremely long. We can eliminate the final thermal anneal. --------------------------------------------------------------------- MIPS CAMPAIGN V Time since Start-up activities, Si and Ge MIPS-905 35 Ge anneal IOC Darks, 160um MIPS-912 15 24 IOC Darks, 70um MIPS-911 30 39 IOC Darks, 24um MIPS-910 15 69 24um Flat - routine, Scan AOR MIPS-914 13 84 160um IC - routine, Scan AOR MIPS-916 13 97 70um IC - routine, Scan AOR MIPS-915 13 110 70um NF Illumination Correction MIPS-313 19 123 Periodic IRU Calibration updates - Pitch PCS-055 36 142 Periodic S2P Calibration - Array_1A PCS-105 12 178 Ge Anneal and recovery MIPS-930 12 190 160um Flux standards MIPS-924 20 10 Routine 24um Flux standard MIPS-920 11 30 70um Flux standards MIPS-922 12 41 Total Power Measurement at Ecliptic Pole MIPS-270 40 53 Ultimate Scattered Light Levels #2 MIPS-341 70 93 Ge Anneal and recovery MIPS-930 12 163 MIPS ERO MIPS-510 120 10 SED Slit Illumination Function MIPS-299 20 130 SED Response Verification MIPS-298 10 150 SED of a Circumstellar Disk MIPS-135 20 160 Periodic S2P Calibration - Array_2A PCS-105 12 180 Ge Anneal and recovery MIPS-930 12 192 70um PSF MIPS-336 447 10 Ge Anneal and recovery MIPS-930 12 210-250(during MIPS-336) Periodic S2P Calibration - Array_1A PCS-105 12 207-247 Ge Anneal and recovery MIPS-930 12 219-259 (delete?) 24um Focal Plane Survey (Fine)#3 MIPS-131 402 10 Periodic IRU Calibration updates - Yaw PCS-055 36 412 Periodic S2P Calibration - Array_2A PCS-105 12 448 Ge Anneal and recovery MIPS-930 12 460 70um NF Focal Plane Survey (Fine) MIPS-138 260 10 Ge Anneal and recovery MIPS-930 12 414 (delete) Shutdown activities, Ge and Si MIPS-992 19 118 Downlink tuning and slews 147 Downlink data 13 Periodic S2P Calibration - Array_1A PCS-105 12 Margin 185 Time allocation for PCRS and IRU calibrations 132 Comments: This campaign centers around a couple of long PSF and FPS tasks. It starts with the standard calibration activities. I like the idea of running the total power measurement test right after the flux standards. It is long enough after the anneal to ensure good stability, and running the test right after the flux standards ought to give us the best possible calibration. I list MIPS-341 next since this task calls for photometry of bright stars, and it seems a good bracketing observation to MIPS-270. MIPS-341 calls for a thermal anneal in its writeup. I'm not sure that an anneal is necessary or makes sense right before these measurements. If that anneal is included, the structure of this campaign should be reexamined. I defer the PSF and FPS tasks until later to ensure good stability of the electronics. Instead, the next anneal cycle starts with an ERO. This is followed by three SED mode tasks. The 70um PSF task is long enough that a thermal anneal is needed halfway through the task. I placed the 24um FPS next to get the timing right on the PCS tasks. If we have no intention of ever looking at the Ge data from the 24um FPS tests, the anneal before MIPS-131 is worthless. --------------------------------------------------------------------- MIPS CAMPAIGN W Time since Start-up activities, Si and Ge MIPS-905 35 Ge anneal CSMM Scanpos Table Upload MIPS-085 5 24 IOC Darks, 160um MIPS-912 15 29 IOC Darks, 70um MIPS-911 30 44 IOC Darks, 24um MIPS-910 15 74 24um Flat - routine, Scan AOR MIPS-914 13 89 160um IC - routine, Scan AOR MIPS-916 13 102 70um IC - routine, Scan AOR MIPS-915 13 115 Ge Anneal and recovery MIPS-930 12 128 160um Flux standards MIPS-924 20 0 Routine 24um Flux standard MIPS-920 11 20 70um Flux standards MIPS-922 12 61 Periodic S2P Calibration - Array_1A PCS-105 12 73 160um PSF MIPS-337 45 85 Ultimate Scattered Light Levels #3 MIPS-342 70 130 Ge Anneal and recovery MIPS-930 12 200 Flux Standard Screening & Linearity Check MIPS-400 378 10 Ge Anneal and recovery MIPS-930 12 190-220(during MIPS-400) Periodic S2P Calibration - Array_2A PCS-105 12 178-208 Periodic IRU Calibration updates - Yaw PCS-055 36 190-220 Ge Anneal and recovery MIPS-930 12 226-256 Confusion Limits Determination MIPS-265 228 10 Ge Anneal and recovery MIPS-930 12 110-130(during MIPS-265) Ge Anneal and recovery MIPS-930 12 118-138 MIPS ERO MIPS-520 240 10 Periodic S2P Calibration - Array_1A PCS-105 12 250 Ge Anneal and recovery MIPS-930 12 262 Scan Map of a Large Galaxy MIPS-295 150 10 Ge Anneal and recovery MIPS-930 12 160 (delete?) 24um Focal Plane Survey (Fine)#4 MIPS-131 402 10 or 160 Periodic S2P Calibration - Array_2A PCS-105 12 188 Shutdown activities, Ge and Si MIPS-992 19 118 Downlink tuning and slews 147 Downlink data 31 Margin 217 Time allocation for PCRS and IRU calibrations 132 Comments: This campaign includes a handful of large tasks. It starts with a scanpos table upload and then the standard calibration sequence. I put the scanpos table upload first so that we can verify that the dark positions are still ok if they get updated. The 160um tasks are the only ones small enough to fit in the space after the flux standards, and they likely involve similar pointing. The flux standard screening is placed next since it involves similar pointing. A thermal anneal has to be run sometime during this task. MIPS-265 involves scan maps at two different Galactic latitudes. The data will be analyzed at all three wavelengths, so it also requires an intermediate thermal anneal. There is no real preference in the ordering of the ERO and the scan map of a large galaxy. I put the ERO first since it is longer and that minimizes the time between the last anneal and the start of the 24um FPS. Again, if we have no intention of looking at the Ge data from the 24um FPS tests, we can eliminate the last thermal anneal.
