Subject: Re: EXPOSURE map (and Data Access)

Hej Niels og Niels Jørgen,

For en god ordens skyld skal jeg lige oplyse at dette svarer til SPR
4777, som jeg sendte i onsdags:
Title: j_ima_iros exposure maps have wrong values
Description:
The exposure maps produced by j_ima_iros (via the parameter
IMA_skyImagesOut = EXPOSURE) does not contain the expected effective
exposure times that should be obtained by multipling the value of the
EXPOSURE keyword (on-axis effective exposure time) by the illumination
map. The actual values are much higher than the value of the keyword
EXPOSURE and seem to have nothing to do with it.
This has eventually an indirect effect on the measure of the exposure
made by mosaic_spec for a given sky-coordinate.
