What is a "bad pixel"? #21

Closed annayqho closed 9 years ago

annayqho commented 9 years ago

flux is infinite
error is infinite
error is negative
do we want to automatically include any of the ASPCAP bad data masks, or are the above three sufficient?

In all cases -- whatever you decide (and @mkness can be helpful here) -- set the ivar to 0 (or some well-defined, small value). Uncertainties should be communicated in the form of ivar (inverse variance)
