| + | ===== Telecon, Jun 13 ===== | ||
| + | * online: Amber, Statia, Woojin, Manuel, Doug, Peter | ||
| + | * data transfer issue at Illinois: | ||
| + | * issue with script | ||
| + | * Peter - testing new code with Woojin | ||
| + | * 3 mars tables: | ||
| + | * 1 is marstb original increments of 25 days | ||
| + | * 2 is marstb2 stops at 115 GHz, increments of 6 hours | ||
| + | * 3 is marstb3 1cm to 260 GHz, increments of 1 hours | ||
| + | * this table is ~5 K cooler than old curves at 115 GHz - see Woojin's plots | ||
| + | * need to check at other freq and if spec index is the same, then ask Brian Butler | ||
| + | * can play with these in new miriad - marstb with table= (need to grab tar files for the tables first) | ||
| + | * will build new binaries for school students tomorrow but it is in CVS now | ||
| + | * fluxtest script is in Miriad now | ||
| + | * fluxcal on science | ||
| + | * memo out this week | ||
| + | * maybe try this on dedicated tracks - send script to Woojin | ||
| + | |||

| + | ===== Telecon, Jun 6 ===== | ||
| + | * online: Amber, Statia, Chat, Nikolaus, Andreea, Woojin, Manuel, Peter, Doug | ||
| + | * Woojin: more 1cm data points and 'new' models from Peter | ||
| + | * still trying to sort out what these new models are: 'most recent models of Glenn Orton and Rafael Moreno' from Brian Butler | ||
| + | * Peter: | ||
| + | * new model from Brian Butler on Mars - Jan 2010 - Dec 2020 in 1 hour intervals at 30-1000 GHz (this is becoming the standard model in CASA) - 11 MB | ||
| + | * miriad program marstb will be able to read this soon - use table= to read 1hr cadence | ||
| + | * Uranus and Neptune models - European + North American collaboration. Hofstader model is more appropriate at 1cm, but this model is better at 3mm and 1mm. | ||
| + | * fluxcal on science: | ||
| + | * copy could take a minute or two but it does happen all in one go - check size of visdata | ||
| + | * multiple corr configs - Doug: sci1 track doppler tracking wasn't set up in first NOISE integration - this is nothing to worry about. sci2...?? wideband channels have a bandwidth of 0...maybe first antenna is being flagged by the system. maybe try re-running uvwide to recalculate the wideband channels from the spectral line channels. uvcat just spectral channels out options=nowide. | ||
| + | * Andreea - looking for comments on everything (incorporated my comments) | ||
| + | |||
| + | ===== Telecon, May 30 ===== | ||
| + | * online: Amber, Statia, Chat, John, Andreea, Doug, Peter, Woojin, Manuel, Tom | ||
| + | * Woojin: added new data points as well as JPL models (from Andreea) to plots | ||
| + | * new data point: Mars track not good (3C84 low elevation, pointing didn't converge) | ||
| + | * 1cm points: 5 or 6 tracks have been tried - planning to add these points soon | ||
| + | * Andreea: looking at 1cm data 2 tracks from May 18 | ||
| + | * estimate the flux of 3C454.3 using Uranus and Neptune separately with different fluxes | ||
| + | * JPL Nep 5.2 | ||
| + | * JPL Ura 5.3 | ||
| + | * CARMA Nep 6.7 (bootflux with nothing specified) | ||
| + | * CARMA Ura 6.6 (bootflux with nothing specified) | ||
| + | * looking now at dataset to figure out which of these fluxes is more appropriate using Mars | ||
| + | * Doug getting Illinois set up | ||
| + | * Peter uses Python package NTHOUGHT? | ||
| + | * fluxcal on science running automated on the high site now, will be running at Illinois soon | ||
| + | * pass on to Manuel once we have fully documented (coming soon) | ||
| + | * Peter contacted Mark Gurwell about Mars models | ||
| + | * passed on to Brian Butler - haven't heard back yet (but Brian Butler is slow to respond) | ||
| + | * been working on table reader in Miriad | ||
| + | * can't officially distribute marstb2.tab (only to 105) until we get okay from Brian Butler | ||
| + | ===== Telecon, May 23 ===== | ||
| + | * online: Amber, Statia, John, Andreea, Doug, Peter, Nikolaus, Woojin, Manuel, Tom | ||
| + | * Andreea: working on 1cm abstest data | ||
| + | * comparision of Uranus and Neptune models from Mark Holfstader show these models agree with eachother within 2% | ||
| + | * Woojin: still needs more abstest data at 1mm | ||
| + | * John points out that models are very similar at 1mm - 1mm data may not tell us much | ||
| + | * perhaps 1mm Uranus/Neptune data could constrain Mars model at 1mm? | ||
| + | * Mars model: | ||
| + | * best bet seems to be szaCalcMars at 1cm, 3mm (diurnal + seasonal var) and marstb at 1mm (seasonal var only) for now | ||
| + | * szaCalcMars uses a table that is almost identical to marstb2.tab, but has additional diameter columns (both of these tables only cover 26-115 GHz) | ||
| + | * marstb uses marstb.tab - this is what is written into datasets by the online system (this table only covers 43 - 345 GHz) | ||
| + | * Peter is working on a miriad program to read marstb2.tab, therefore making the diurnal variation mars model available in miriad | ||
| + | * Peter will contact Mark Gurwell about getting diurnal variation Mars model good out to 1mm | ||
| + | * fluxcal on science: | ||
| + | * Doug got permissions worked out - we should be getting new datasets today | ||
| + | * python install needed: Doug will check, but the best bet may be to put our own local install of python in our area | ||
| + | * getting julian dates on the high site: high site date calculations are done in C, so we should just use a local copy of a python package to do it. | ||
