File Naming Schemes¶
Exposure file names¶
The names of the exposure level data are constructed with information from the science header of the exposure, allowing users to map it to the observation in their corresponding APT files. The ASDF file naming scheme for the Exposure products is:
r<ppppp><cc><aaa><sss><ooo><vvv>_<gg><s><aa>_<eeee>_<detector>_<prodType>.asdf
where
ppppp: program ID number
cc: Execution Plan number
aaa: Pass Number (within execution plan)
sss: Segment Number (within pass)
ooo: observation number
vvv: visit number
gg: visit group
s: sequence ID (1=prime, >1 parallel)
aa: activity number (base 36)
eeee: exposure number
detector: detector name (e.g. WFI01, WFI02, …)
prodType: product type identifier (e.g. ‘uncal’, ‘cal’)
The standard <prodType> for the pipeline are uncal and cal, for the input products and resulting calibrated product. There are optional suffixes for intermediate products that are not routinely produced by the pipeline and are based of the processing level and can include dqinit, saturation, linearity, jump, darkcurrent, rampfit, assignwcs, flat, and photom.
An example Exposure Level 1 upcalibrated ASDF file name is:
r0000101001001001001_01101_0001_WFI01_uncal.asdf
An example Exposure Level 2 product ASDF file name is:
r0000101001001001001_01101_0001_WFI01_cal.asdf
