I would like to calibrate a large number of AVHRR ESA Sharp images in Batch mode using the ENVI_AVHRR_CALIBRATE_DOIT procedure. These image data are associated to a leader file needed to make the calibration process. When I run the batch I have to supply interactively the name of the leader file for each image. This could be avoided if the procedure should accept a keyword realated to this leader file, but this point is not included in the description of ENVI_AVHRR_CALIBRATE_DOIT. Is there any way to solve this small problem?
