Level 3 Calibration Status
Outline
Schema Definitions ¶
This type is an object with the following properties:
flux
object Required Flux Scale Application Step
Step in romancal that applies the scaling factor(s) necessary to convert from units of data numbers per second (DN/s) to megaJanskys per steradian (MJy/sr).
This node must validate against all of the following:
outlier_detection
object Required Outlier Detection Step
Step in romancal that detects and flags outliers in a stack of rate images.
This node must validate against all of the following:
skymatch
object Required Sky Matching Step
Step in romancal that matches sky background levels of each input image and derives scaling factors to equalize overlapping regions.
This node must validate against all of the following:
resample
object Required Resampling Step
Step in romancal which resamples and coadds each input 2D image based on its WCS onto a grid, in order to combine multiple images into a single coadded product.
This node must validate against all of the following:
