0 Assigned ID: 1607 ----- Attempting Submission 1 (Fri Mar 01 18:13:23 GMT 2013) ----- HST Phase I Proposal 1607 (cygloop.apt) successfully submitted. Please note that the Cygnus Loop position is 10" from that specified in the Phase I proposal. We concluded that Position 1, rather than Position 2 from our Cycle 19 program was preferable because it is brighter in the He II line (which is more challenging than C IV) and because there will be less complication of the interpretation due to carbon atoms sputtered from dust. These comments still apply: June 29, 2013 1021890439 ----- Attempting Submission 1 (Sat Jun 29 13:49:20 GMT 2013) ----- As explained severral times before, there are 3 warnings that acquistions should probably be performed before the COS observations. I believe that that does not apply, because these are extended targets and it would be impossible to peak up the counts. Ion Temperatures in a Collisionless Supernove Remnant Shock Wave Electrons, protons and heavy ions can all have different temperatures behind a collisionless shock. The temperatures are important for understanding the physics of the shock and for correctly interpreting observations in terms of shock parameters. They also bear upon the acceleration of different species in the Cosmic Ray population. We propose to obtain a deep enough integration to measure the kinetic temperatures of C IV and He II in a 350 km/s non-radiative shock in the northern Cygnus Loop where we have extensive complementary H alpha and X-ray data. We wish to observe a position in the Cygnus Loop that we observed for 1 orbit under a Cycle 19 proposal for 9 additional orbits in order to obtain high enough signal-to-noise to measure the line widths of the He II 1640 and C IV 1550 lines. All the observations will be made with th COS 160M grating, 1577 tilt. We also wish to observe the planetary nebula NGC 6853 for one orbit in order to obtain a reliable measurement of the instrument profile of COS when the PSA is filled with diffuse emission. ISM AND CIRCUMSTELLAR MATTER Default false false false false false SUPPORTED ISM SHOCK FRONT SNR The Cygnus Loop position is slightly different (10 arcsec) than that listed in the proposal. We have decided that Position 1 from our Cycle 19 HST program is a better option than Position 2 listed in Table 1 of the proposal because the He II line (the more challenging observation) is brighter at Position 1 and because there is less possibility of confusion with C IV produced by carbon ions that come from sputtering of dust grains. Positions 1 and 2 are separated by 10", so this is a very slight change. Also, we have added the 0.2" proper motion appropriate for an observation next year. As the emission fills the aperture, this proper motion correction does not have to be precise. APT warns that acquisitions should be performed. This is an extended source, and acquisition is not feasible. J2000 J2000 C IV 1550 and He II 1640 fluxes observed with COS are 1.12e-15 and 1.01e-15 erg/(cm2 s), respectively. CALIBRATION EMISSION LINE NEBULA POINT SPREAD FUNCTION This observation is designed to obtain the instrument profile of COS with the G160M grating for an extended source that fills the aperture. The line width in this planetary nebula is small compared to the roughly 200 km/s resolution of COS with the PSA aperture filled. APT warns that target acquistion is recommended, but this is a very large extended source, so acquistion is not feasible. J2000 J2000 C IV 1550 and He II 1640 are 1.4e-14 and 3.0e-14 ergs/(cm2 s) in the COS aperture respectively COS/FUV Spectroscopic No No G160M 1600 COS/FUV Spectroscopic No No G160M 1600 /home/raymond/prop/HST21/OP-cache/phaseii_draft-v01.xml The scheduling data was generated by CASM 21.2.

The purpose is to obtain an accurate instrument profile that can be used to deconvolve the profile of the Cygnus Loop shock wave. The position selected is based on IUE Small Aperture exposure SWP17420, and it is 49" W and 27" S of the central star.
