----- Attempting Submission 3 (Fri Dec 04 18:29:46 GMT 2015) -----The warning about inefficient use of FPPOS come about because each orbit starts with FPPOS=1 and a switch from 4->1 is made at the end of each orbit
The coordinate warnings probably are because ACQ/IMAGE instead of ACQ/SEARCH is suedMapping the circumgalactic medium of two large spiral galaxiesThe distribution and kinematics of the gas flows around galaxies provide important observational constraints on models of structure formation and galaxy formation/evolution. Current observational constraints on the motions, density and ionization of material around galaxies are based on ensembles consisting of many single sightlines crossing halos of individual galaxies of different types, masses and orientations. One of the original goals set for COS was to take the next step: mapping the gas around a single galaxy using multiple sightlines, to get around the biases affecting ensemble studies. We propose a 28-orbit observing program to obtain COS G130M spectra of 9 quasars that sample HI at log N(HI) = 13-15 in the circumgalactic medium of the nearby isolated edge-on ~3 L* spiral NGC2770 and the nearby, isolated face-on ~2.5 L* spiral NGC3631, at impact parameters of ~200 to 400 kpc (0.7-1.5 times the virial radius). We will determine the column densities, kinematics and line widths of HI Lya as function of impact parameter, without confounding factors due to mixing different galaxies. We will compare these measurements with results of cosmological simulations of similar-sized galaxies, providing a unique view of the density structure of and large-scale gas flows around isolated, large spirals.There are 9 targets in this program, which are to be observed for 2, 3, 4 or 5 orbits each.
The setup is as follows:
First do an ACQ/SEARCH, with SCAN-SIZE=3, with exposure times calculated with the COS ETC, G130M-1327 to get S/N=40, using the target flux as found from GALEX data.
Next do ACQ/PEAKXD and ACQ/PEAKD to completely center.
This takes about 900 seconds.
Then take spectra with central wavelength set to both 1327 and 1291, in order to get the maximum wavelength coverage (1134 to 1468 A), even though at the edges the S/N will be lower. However, the extra 40 A each end is useful to be able to identify more Lya or metal lines.
For a two orbit target, the first orbit has a 1327 setting, using FP-POS=1,2,3,4. Then in the second orbit 1291 is used with FP-POS=1,2,3,4 for half the orbit each.
For a three orbit target, the first two orbits have 1327 FP-POS=1,2,3,4, while the third orbit uses 1291 FP-POS=1,2,3,4
For a four orbit target, the first two orbits have 1327 FP-POS=1,2,3,4, while the third and fourth orbit have 1291 FP-POS=1,2,3,4
For a five orbit target, the first three orbits have 1327 FP-POS=1,2,3,4, while the third and fourth orbit have 1291 FP-POS=1,2,3,4ISM IN EXTERNAL GALAXIES12falsetruefalsefalseSUPPORTEDGALAXYQSONOJ2000J2000FUV=0.14E-14GALAXYQSONOJ2000J2000FUV=0.60E-14GALAXYQSONOJ2000J2000FUV=0.09E-14GALAXYQSONOJ2000J2000FUV=0.15E-14GALAXYQSONOJ2000J2000FUV=0.28E-14GALAXYQSONOJ2000J2000FUV=0.16E-14GALAXYQSONOJ2000J2000FUV=0.09E-14GALAXYQSONOJ2000J2000FUV=0.08E-14GALAXYQSONOJ2000J2000FUV=0.26E-14COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291/Users/wakker/laptop/telescopes/hst/23_cycle/PHASE2/OP-cache/halos-v01.xmlThe scheduling data was generated by CASM 23.2.CASM was run in Phase II mode.(Tic-Visit
