12796( 12) - 06-Apr-2012 18:57:27 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 12796 Version: 12 Check-in Time: 06-Apr-2012 18:57:27 STScI Edit Number: 8 Title Second COS FUV Lifetime Position: Focus Sweep Enabling Program (FENA3) ------------------------------------------------------------------------------------ Type Cycle CAL/COS 19 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Cristina Oliveira Space Telescope Science Institute CoI: Ms. Azalee K. Bostroem Space Telescope Science Institute Y ------------------------------------------------------------------------------------ Abstract This program verifies the focus at the new lifetime position by performing focus sweeps with the G130M, G160M, and G140L gratings. Ray trace models predict that the best focus at the new position is within +/-200 focus steps from the current absolute focus. The focus sweeps performed in this program scan the focus at 100 focus step increments around the offsets predicted by ray-trace models and at 200 focus step increments at the extremes. ------------------------------------------------------------------------------------ Observations Description ------------------------ A focus sweep with the G130M/1309 setting is executed in visit 01 and a focus sweep with the G160M/1600 setting is executed in vis 02. Both focus sweeps are executed at a position that correponds to the spectra moving +35 pixels from the current location. This is accomplished by specifying XAPER=-62 and Y_POSTARG=+2.94. The visits in this program should execute 3 weeks after visit 01 of program 12795 (FENA2) executes, preferably in the Mar 12 2012 SMS. Program 12796 should finish executing at least 3 weeks before 12797 executes. As a result of analysis of data acquired in visit 01 of program 12795 the value of XAPER was changed to -73 and the value of Y POS TARG to +3.5". Visit 03 is a focus sweep of the G140L grating, using AzV 75. A new version of APT became available after visits 01 and 02 executed, which takes into account the different lifetime positions, without having to use special commanding, in addition to a FWS update which occurred on the weekend of Mar 25 and which allows different lifetime position. Vis 03 was prepared with the new APT version. Also, after visits 01 and 02 executed it was noted that the detector was being scrubbed by those data, at the new lifetime position. For this reason it was decided to execute vis 03 at a lower operational voltage. CONSTRAINTS: Visit 03 of 12796 should execute on the SMS of Apr 16 2012. Visits 01 and 02 of 12797, which are also executing on the SMS of Apr 16 2012, 12796( 12) - 06-Apr-2012 18:57:27 - [ 2] should execute BEFORE visit 03 of 12796. This is because visits 01 and 02 of 12797 measure the PSA to WCA offset, which is gain dependent, and visit 03 of 12796 is likely to scrubb the detector, i.e., lower the gain. Even though the PSA to WCA offsets will need to be adjusted in the future it is better to determine values that will be closer to reality once operations at the new lifetime position start.

SAA-FREE scheduling only. Analysis of visits 01 and 02 of 12796 indicates that there are discrepancies between the focus modeling and the focus offsets predicted from these data and so a focus sweep with the G140L needs to be executed. The target used, Azv 75 is brighter than but similar to the target used in the G140L focus sweep in program 12080. The focus sweep in 12796 applies focus offsets of -800 to +800 focus steps. The absolute focus for G140L/1105 is -370. Target count rates: In the G140L/1105 setting the target's local count rate is 0.75 cts/sec/pix which is 12% above the local limit of 0.67 cts/sec/pix. This violation happens where the P-Cygni profile from N V falls. In this kind of stars the strength of the P-Cygni profile is not supposed to increase, if anything it is the absorption that changes. Given that this target was previously observed with STIS E140M the Team decided that the 12 % local count rate violation was not an issue. The global count rate in seg A is slightly above the 15, 000 cts/sec at 16040 cts/sec but that should not be an issue either. BOP and Field This target falls in a very crowded region of the SMC and as such there are no GSC2 or Galex targets to use with the BOT. The photometric survey of the Magellanic clouds by Zaritsky et al. 2002 (AJ, 123, 2, 855) available in vizier (J/AJ/123/855) observed the AzV 75 field and can be used to clear it: Within 11", which is the radius of the region that needs to be cleared for the PSA (when the TA exposures are taken into account) there are 12 sources. One of them is the target (V=12.756). All the other sources are fainter than V=18.0 and even assuming unredened OV there are not BOP issues. To clear the BOA region we only have to consider targets brighter than V=10 according to table 10.3 of the COS IHB. According to the catalog in Vizier there is only 1 source brighter than V=13 within 30" other than the target. This source has V=12.956 and so should not pose a problem for the BOA.

The special commanding here sets the the nominal high voltage for this visit (HVNOM) for segments A and B (ENDCTSA and ENDCTS B) to 167 and 163, respectively. 403s is the correct rampup time for 162/159. An allow 3 additional seconds for every positive unit of offset is required. Therefore, the rampup time is 403+(167-162)*3 = 418 *** This exposure was copied from vis 01 of 12797 where the HV is lowered to the same values **** ------------------------------------------------------------------------------------------------------------------------------------ 2 AZV75 COS/FUV ACQ/PEA PSA G140L 1105 LIFETIME-POS=ORIGINAL 1 1 S AFTER BY 0 S TO 900 S KXD ------------------------------------------------------------------------------------------------------------------------------------ 3 AZV75 COS/FUV ACQ/PEA PSA G140L 1105 NUM-POS=5, STEP-SIZE=1, 1 1 S AFTER BY 1 S TO 4000 S KD LIFETIME-POS=ORIGINAL ------------------------------------------------------------------------------------------------------------------------------------ 4 NONE COS ALIGN/O FOCUS=-800, 1 0 S AFTER BY 1 S TO 4000 S SM LIFETIME-POS=ALTERNATE ------------------------------------------------------------------------------------------------------------------------------------ 12796( 12) - 06-Apr-2012 18:57:27 - [ 14] Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exp | Target | Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Num | Name | Config | Mode | or FOV |Element |Waveln.| Parameters |Exp| | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 5 AZV75 COS/FUV TIME-TA PSA G140L 1105 BUFFER-TIME=100, FP-POS=3, 1 200 S AFTER BY 1 S TO 4000 S G LIFETIME-POS=ALTERNATE Comments: COS.sp.393770 for t exposure = 190 sec, S/N=65 at 1310 per resel COS.sp.393448 for t exposure = 147 sec, S/N=57 at 1310 per resel COS.sp.393677 for t exposure = 110 sec, S/N=49 at 1310 A per resel.
