Student Hera: Analyzing Images - Activity 4

Activity 4: Manipulation of
  • Open image using Pow Plot.
  • Manipulate the image to look for new detail.
  • Record the manipulations and results in a chart as you work.
  • Answer the questions after completing the manipulation of the image.

Manipulation Mode
(duplication, color change, scale change, etc.)
Results & Observations of Image

Activity 4 Questions:
  1. Describe whether or not you feel manipulation of the image was helpful or not helpful to you in looking for new information in the Supernova Remnant (SNR). Be specific with examples from your observation notes.
  2. Elaborate on which of the image manipulations was most helpful and what resulted from that manipulation of the SNR image.
  3. Evaluate the effectiveness of manipulating this image versus the other 3 images. Was manipulating this image more or less helpful in looking for new information in the SNR image?
  4. Explain if there was anything visible in the image after manipulation that was not visible to you before manipulation. If so, what does it appear to be?
