EXPTIMEis required by solarsoft but strongly discouraged by SOLARNET
hola! is it true that we do not have an entry for 'exposure time' in the header metadata?
9:22 AM morning
🙂no, we have that
9:23 AM ok. aparently Lucia mentioned in the questionaire that we do not have it
9:25 AM what we don't have is the EXPTIME keyword. SOLARNET discourqages using it, as it is unclear whether it means single frame exposure or total exposure time what we do instead for GRIS (as recomended by solarnet) :
XPOSURE = 300.0 / [ms] Accumulated exposure time TEXPOSUR= 100.0 / [ms] Single-exposure time NSUMEXP = 3 / Number of summed exposures
i think for GSJC we added the EXPTIME keyword specifically for lucia
9:28 AM ok. i believe what LK meant is that 'exptime' is/was widely used and i guess SolarSoft requires it. When Morten was around there was some agreement with LK to include duplicates of some keywords. I bet 'exptime' should be one of them..
9:28 AM yes it was
9:28 AM exactly
schaffer 9:26 AM i think for GSJC we added the EXPTIME keyword specifically for lucia 9:29 AM is there a specification or definition document on which keywords solarsoft expects? we could try to check whether it conflicts with SOLARNET once we start nailing down the standards
9:31 AM i don't know. should be checked. it is also true that SOLARNET should clarify how to deal with this issue..
