Subject: mipl data reformatting

Hi Dave,

We had a discussion here about we'd like the mipl data to
be reformatted for use w/ the DAT. There is a second question
we should talk about today, which is the nature of the ramps
in the mipl files (see below). 

For the reformatting into extension files issue, there are 3 basic
categories: Scan, Phot, IERs.


SCAN:
	One fits file per array per scan leg. I think
	that means equivalently one file per array per
	exposure.

PHOT, SED, TPM:
	One fits file per array per primary band per AOR.
	By primary band I mean the band was selected for
	the AOR. If the AOR calls for 24 and 70microns,
	then there are 2 primary bands. We'd want two sets
	of fits files, each set containing 3 files (one for
	each array), the first set containing the data from 
	when the 24um array was pointed at the target, the 
	second set from when the 70um array was pointed. In 
	this case each file could include data from more than 
	one exposure command, e.g. the pre-first-stim exposure, 
	the first dither pattern, the next pre-first-stim 
	exposure, and the second dither pattern.

	CLUSTER / RASTER-MAP: 
		Include DCEs from all cluster/raster pointings
		in a single file, subject to provisions above.
IERs:
	These will usually just need to be packaged into files
	containing single exposures, but we need to actually go
	through the IERs we have and decide what is needed for
	each of them, and then capture that information someplace
	where it can be used during IOC.
