Study 000149:

Slit/slot: 40" slot
No of fine mirror steps: 5
Step size: 40"
Total spatial width: 240"

Compression: DCPM
Data rate:  49.4965 kbits/second

Notes to planners
-----------------

Both of the CME onset studies:

cmeo_slot and
cmeo_slit

are designed to observe coronal dimming (on
the limb of the Sun) which is associated with mass ejection. Pointing should
be at an active region on the solar limb. In solar-y, the raster should be
centred on the active region. In solar-x, the raster should overlap the limb
slightly, but have the majority of the raster above the limb.

We are trying both slit and slot rasters to observe coronal dimming. They do
not have to be run at the same time. However, it would be beneficial for
both studies to be run on the same active region once (minimum 6 hours
each), so that we can determine which study is best for this type of
observation.

In each study, there is one raster, which should be repeated to fill the
available time.
