----- Attempting Submission 2 (Fri Mar 01 17:17:23 GMT 2013) -----Changed visit 1 and 5 FPPOS for 1291 setting to 1/2 instead of 3/4 to even things out757713468----- Attempting Submission 1 (Fri Jun 14 20:10:37 GMT 2013) -----
----- Attempting Submission 2 (Wed Nov 06 17:51:36 GMT 2013) -----For all target two different G130M central wavelenghts are used, 1291 and 1327, in order to
maximize the wavelenth coverage. In each orbit 2 different exposures with two FP-POS positions
are used. This means that for a 2 orbit target, FP-POS=3&4 are used for 1291 and 1327, but not
FP-POS=1&2. For a 3 orbit target, FP-POS=1,2,3,4 are used for 1327, 1&2 and 3&4 in two visits
each for 1291 . For four orbit target FP-POS=1,2,3,4 are used for both central settings.
I tried using 1,2,3,4 in a single orbit, but that was too expensive exposure-time wise.Constraining the size of intergalactic clouds with QSO pairsThis proposal aims at a geometric estimate of the size of intergalactic absorbers (clouds) near redshift 0, which make up the 10^4 K photoionized phase of the intergalactic medium (IGM). Theoretically the size of these clouds is expected to be ~170 kpc at log N(HI)=13.3 and ~20 kpc at log N(HI)=16. So far, this has only be tested observationally for a few rare systems in which metal-line absorption allows photoionization modeling. We propose to observe 4 QSO pairs (7 new QSOs and 1 archival dataset) separated by 2 to 5 arcmin (corresponding to ~20 kpc at cz=1500 km/s). Using these data we can set a completely independent, geometrical, constraint on the cloud sizes, even if no metal lines are seen. The data will further allow determining velocity gradients in single clouds.There are 7 targets in this program, which are to be observed for 2, 3 or 4 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=3 and FP-POS-4. Then in the second orbit 1291 is used with FP-POS=3 and 4 for half the orbit each. I tried using FP-POS=1 through 4, but this took about 500 seconds off the exposure time.
For a three orbit target, the first orbit has 1327 FP-POS=1 & 2, while the second orbit has 1327 FP-POS=3 & 4, and the third orbit uses 1291 FP-POS-3 & 4.
For a four orbit target, the first orbit has 1327 FP-POS=1 & 2, while the second orbit has 1327 FP-POS=3 & 4, the third orbit uses 1291 FP-POS-1 & 2, and the fourth orbit has 1291 FP-POS 3 & 4.QUASAR ABSORPTION LINES AND IGMDefaultfalsetruefalsefalsefalseSUPPORTEDGALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=3.3E-15 z=0.110GALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=2.2E-15 z=0.098GALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=7.9E-15 z=0.284GALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=3.3E-15 z=0.147GALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=6.9E-15 z=0.140GALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=2.6E-15 z=0.851GALAXYLYMAN ALPHA CLOUDQUASARJ2000J2000F=5.2E-15 z=0.08COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291COS/FUVSpectroscopicNoNoG130M1291The scheduling data was generated by CASM 21.2.CASM was run in Phase II mode.(Tic-Visit
