+The evening 'A' calibration sequence includes the LFC and Etalon
+frames (and flats) that are necessary to start the nightly drift
+calibration.  The 'C' calibrations contain the UNe lamps, which are
+only present as an emergency backup source in case the LFC is offline. 
+Taking the 'A' sequence is critical; skipping the 'C' sequence if you
+are crunched for time is OK, although that sequence has been timed to
+fit within a typical stack time.

 * The RA performing Ops in the afternoon will typically start the eveening HPS cal set. This will take about 1h10m to complete.

+We have added an additional script (hpf_takeLFCHRCalExposure.sh)
+that will take a LFC exposure through the calibration fiber (~2 minutes
+to complete).  This should not interfere with any other telescope
+operations, as it is entirely internal to HPF.  If you find yourself in
+a situation similar to last night, you can run this stand alone script
+a few times while a different primary operation is happening (e.g. LRS
+or VIRUS exposure, slew, or other telescope setup).  That will at least
+provide a few LFC reference points to tie the drift calculation to.
+
+The script accepts an optional argument - N - where N is the number of
+ramps you wish to take. e.g.  {{{ ./hpf_takeLFCHRCalExposure.sh 3 }}}
