Through the MER and Phoenix Analyst's Notebooks, sequences of images taken by Navcam, Pancam, Microscopic Imager, and Hazcam can be downloaded as multi-band ENVI formatted images for use with ENVI image processing software.

 

The images can be downloaded under Sequence Download in the Product Sequence menu for any sequence of images. By going into "Sol Summaries" (for Spirit, Opportunity, or Phoenix), you will be able to select a sol and then view the data products from the "Report" menu. By choosing a sequence of more than one image, the product sequence overview page will be displayed. Click on "Sequence Download" from the sequence menu (on the left of the overview page), and the various download formats of the images will appear. You can choose to download images from the left eye, right eye, or both.

 

For example, from Opportunity sol 262 let's download the Pancam data for sequence P2832 that starts at SCLK 151430923. We will save the data as an ENVI image.

The above screen shot shows the window after clicking the desired Pancam sequence (1P151430923ESF36CLP2832L2C1) in the data products. Once you click on "Sequence Download," your screen will look like the below image.

We can download data as ENVI image and header files from here. (These two files must be downloaded separately.) Let's display the data in ENVI by opening the File menu and then clicking "Open Image File." After loading the band, the image will appear (see below).
