Website for 61-inch: ================================= - http://james.as.arizona.edu/~psmith/61inch// Questions for Fink and/or Meech: ================================= - FITS headers do not indicate a filter. No filters used? - FITS headers state the LPL CCD was used. Was this one of the old but replaced "Direct imaging CCDs", as mentioned at the telescope's website? Image Orientation: ================================= Using the fr94d029.fit image from June 12 1994 06:23:58 UT, the comet was located at RA = 13 10 21.6 and DEC -1 37 58.7. I used USNO A2.0 catalog and charting online service at http://www.nofs.navy.mil/data/FchPix/ to generate a 10x10 arcmin sky chart. Sky charts and ephemeris are stored here: /n/tempel/stefmcl/pds_work/bigelow94_fink_9p/*sky_chart*jpg /n/tempel/stefmcl/pds_work/bigelow94_fink_9p/eph_1994Jun12_14.txt The fr94d029.fit image, at 512x512 pixels, is about 8.5x8.5 arcmin. All other images have a much smaller FOV. A comparison of fr94d029.fit with the USNO sky chart shows that when the FITS image is displayed in IDL with: SAMPLE_DISPLAY_DIRECTION = "RIGHT" LINE_DISPLAY_DIRECTION = "UP" AXIS_ORDER_TYPE = "FIRST_INDEX_FASTEST" Then North is Right (increasing DEC with increasing AXIS1/col number) and East is Up (increasing RA with increasing AXIS2/row number To get North Up and East Right in an IDL display, rotate the image 90 degrees counter-clockwise. Original Email from Mike ================================= From ma@astro.umd.edu Thu Feb 19 09:19:58 2004 Date: Wed, 18 Feb 2004 18:23:20 -0500 From: Mike A'Hearn To: "McLaughlin, Stefanie" , "Belton, Michael J. S." , "Meech, Karen J." Cc: "A'Hearn, Michael F." , "Farnham, Tony" Subject: Tempel 1 images Colleagues, I have now received 6 FITS images of Tempel 1 from Uwe Fink. They are all from 1994, on Mar 17, Apr 12 (2 images), Jun 12, Jun 13, and Jun 14. All are in FITS format. Stef -- they are in /home/ma/tmp/t1images/. Would you please collect them for our archive and make sure they are saved? Everyone - is anyone interested in working on these images? Karen - it is not clear whether your student is better occupied working through your data right now or starting on these. I don't know who else has time free now. I can talk to a few of our people, but the only ones with experience finding features in images of cometary comae are quite busy (Tony, me). Mike -- Michael F.
