############################## PROJECT INFO ################################## Run: 6th GISMO pool Project: 199-14 PI: Israel Hermelo Contact: hermelo@iram.es Target: The dust SED of dwarf galaxies: NGC4449 Allocated time: 9 hours ########################### WEATHER CONDITIONS ############################### In the proposal we asked for pmw < 7 mm. => tau_225GHz = 0.0405 * pmw + 0.0105 ~ 0.3 Therefore, this project is meant to be observed only when tau is < 0.3. However, in conditions of good stability, values up to tau ~0.5 are acceptable. In case of doubt ask the AoD. ######################## OBSERVATIONS BOOKKEEPING ############################ We prepared a script to observe our target (see ~/199-14/observe_NGC4449.pako) consisting of 3 rounds of on-the-fly maps. The scanning direction adopts 3 different values (0, 45, and 90 degrees) within each round in order to avoid striping artifacts. The execution of the script will take ~90 minutes (3 rounds, 3 scanning directions, 10 min per map), so "observe_NGC4449" must be executed 6 times to reach the allocated time. If you observe this project, please keep the number of repetitions (Nreps) updated.

Check the value of the FWHM. If FWHM > 21 arcseconds then the telescope needs to be focused (see the wiki). Load the observing script: PAKO> @ ~/199-14/observe_NGC4449 Once the script is done go to the pointing source and do a pointing. Please, DO NOT forget to check again if the telescope needs to be focused. Thank you very much! Israel Hermelo
