Outline
Schema Definitions ¶
This type is an object with the following properties:
zodiacal_light
number Required Estimated Zodiacal Light Surface Brightness (MJy/sr)
A model estimate of the Zodiacal light contribution to the sky background in units of MegaJanskys per steradian (MJy/sr).
image_median
number Required Median Image Value (DN/s)
Median image value in units of data numbers per second (DN/s).
image_rms
number Required Image Mean Absolute Deviation (DN/s)
Mean absolute deviation of the image values in units of data numbers per second (DN/s).
good_pixel_fraction
number Required Fraction of Good Pixels
The fraction of pixels on the science portion of the detector for which the data quality bits are do not include a value corresponding to “DO_NOT_USE”.
