Michelson Science Center: Web V2 Calibration

webCalib: Calibration for V2 Observations

This interface allows you to run wbCalib/nbCalib on your KI or PTI data. See the data calibration guide for an overview.

What you need before you start:

1. A single file with SUM and/or SPEC data. Multiple .sum and.spec files can be concatenated before uploading.
2. Either a calScript file or a catalog file (also known as a schedule file). You can create a calScript file by hand or by using csAdHoc in getCal.
3. (Optional) A .baseline or .bline file. If no file is given or the file has format errors or inadequate data, webCalib uses a baseline default (K1K2 for KI data and PTI_NS for PTI data).

Note to users with many sources: you should consider downloading and installing the V2Calib package for faster processing. It is available from the MSC Download Portal.

Inputs ?
