Some of you running quite short exposure times have noted that the different ways of getting the exposure time are not quite consistent with each other. This has now been fixed so that calling the getexp method i.e. data->getexp() should give the most accurate exposure time available.
!Search EIS studies
At line 67 changed one line
For those who want to know the background for this issue I provide a little more info. There are three different exposure times for EIS: 1) the requested exposure time, set in eis_mkraster (or whatever) previously available as data->getexp() 2) the difference between the shutter open time t1 and shutter close time t2 ((*(data->getaux_data).ti_2)-(*(data->getaux_data).ti_1))/512 and 3) the exposure time as measured by the mechanism and heater control unit *(data->getaux_data).mhc_dur/1.e6.
*[Searching for EIS Studies on the Web |EIS_Web_Search]
At line 69 changed one line
The latter is the most accurate and has now been implemented as the default when calling data->getexp().
