Project number: 071-11 PI name and e-mail: Rocio Jurado jurado@iram.es ****************************************** * 1.- scientific summary of the project: * ****************************************** The goal of this project is to check whether there are differences in the chemistry in four different positions, within the outflow and the streamers of M82, because these regions have different origins (the streamers are accretting material to the disk, since the outflow is ejecting gas processed by the center of the galaxy). We propose to integrate until reaching a rms of 1mK on each one of the 4 proposed positions to detect the molecules HCO+, HCN, HNC, CS, CH3-OH and C2H... Since we are interested in obtaining data of all the regions we want to integrate in two blocks of 90min in each one of the regions. Please, observe once each one of the positions before starting a second run. This README file will be updated when the observations will be done. Please, fill up this table every time this project is observed. Thank you very much ! ****************************************** * 2.- Summary of the observations: * ****************************************** First Setup, (Receiver1.pako, HCO+(1-0)) Position Observed once ? Observed twice ? (Mark a X) M82-3 -- -- M82-5 -- -- M82-7 -- -- M82-13 -- -- Second Setup, (Receiver2.pako, CS(2-1) and CS(3-2)) Position Observed once ? Observed twice ? (Mark a X) M82-3 -- -- M82-5 -- -- M82-7 -- -- M82-13 -- -- ******************************************************** * 3.-Step-by-Step Instructions to observe the project: * ******************************************************** OBSERVING SESSION : @~/071-11/Setup @~/071-11/Receiver1 @~/071-11/Backend cal start !Ask the operator to tune the telescope source A_PLANET @~/071-11/pointing ! Enter the corrections provided by MIRA. set pointing XX YY ! Ask the AoD if you have any doubt. !! Once the pointing is done, please do a focus !! On a strong planet0 @~/071-11/focus set focus FF source A_STRONG_AND_NEARBY_SOURCE !! Perform now a pointing on @~/071-11/pointing !! A STRONG AND NEARBY SOURCE. set pointing XX YY @~/071-11/Backend source M82-3 !! Select one of the positions on M82. !! Please, check the table at the beginning of !! this README file. @~/071-11/onoff ! one execution (~90 min) source A_STRONG_AND_NEARBY_SOURCE !! Perform now a new pointing on @~/071-11/pointing !! A STRONG AND NEARBY SOURCE. set pointing XX YY source M82-7 !! Select another one of the positions on M82 @~/071-11/onoff !! and integrate during another run (~90 min) ... Please, fill the table above every time one position is observed... Once the four positions are observed once, observe them again, please... Once that you have observed all the positions, and that a good rms is found (i.e. 5mK for the HCO+ line) switch to the second setup: @~/071-11/Receiver2 And observe twice each one of the four positions.... THANK YOU VERY MUCH !!!
