Parallax of Asteroids JS9(AiM) (First Part - Second Part)

Observation site 1: Observation site 2:        Initial assessment and orientation:
  • Upload the images from Teide in observation site 1:
    JS9-menu :   File ➔ open local ...
    Search the folder and activate all (nine) images with [open].
  • JS9-menu :  View ➔ Blinking
    allows an overview of the loaded recordings.
  • Check [ ✓ ] blink on every loaded image.
  • A tick at [ ✓ ] Blink Images shows that there are fixed stars and moving objects.
    Set "blink rate" to "0.1".
  • Check if the picture numbers are shown in the correct order.
    (The order of the images can be changed by holding down the left mouse button.)
  • Describe your observations in key words!

  • Upload the images from Cerro Tololo (lsc) in observation site 2:
    JS9-menu :   File ➔ open local ...
    Search the folder and activate all (nine) images with [open].
  • Carry out all the above steps also for observation site 2 and
    describe your observation in comparison to observation site 1 in key words!

    The images from Cerro Tololo/Chile (observation site 2) are a little unsteady. This may be due to strong winds during the recording.
    You can try to stabilize the images by using :   WCS ➔ wcs reproject ... ➔ all images in this display, using wcs   
    ( WCS stands for World Coordinat System: The program aligns the images according to the sky coordinates provided in the FITS header. )
    Attention: Depending on the speed of your computer, this may take some time!
  • Put your keywords into a flowing text.
  • Search the internet for information about asteroid 7335 and summarise the most important points.
  • Find out the meaning of PHA and write it down.
  • Complement your work with a picture of 7335 from Teide/Tenerife and a picture of 7335 from Cerro Tololo/Chile.
  • Mark the position of asteroid 7335 in both images.
  • Label both images: Name of the object, observation site, date, time in UT.
  • Explore and describe the observation sites (picture, map, ...).
